There seems to be dither artifacts in this image if you look close enough?

I will say, this looks really pretty, I really can't fault much. Just be consistent with shadows, the gate and the support pillar like walls don't cast one at the moment.
And this, which will take a few seconds to fix.

There is still a lot that you can improve. Right now though it might be a good idea to break this down into smaller, more manageable sections and just focus on getting those sections looking right.

For example, I'd just focus on the head. Right now anatomically if you stripped away the clothing, I don't know if you could realistically fit a mouth and chin on that face, and I have to ask myself if the forehead is large enough. I know its all relative, because you're not necessarily going for realism, the big eyes being the biggest example,  but it won't hurt looking at references of faces to give yourself a rough idea of better proportions.

Also try and work on creating better lines and shapes. The hoodie part of the jacket has a very jagged look to it because your lines are all over the place. Try and clean it up and make sense of how the hoodie would actually sit and hang on the face, because right now, on the characters right side of the face you can see more skin than the other side. Its just those little things that if you clean up would be easier for us to look at as consumers.

Lighting and shading is still a big issue, its not somethings I spent much time on to fix in my edit last time, for example the chest looks blotchy, because the transition from light to dark isn't smooth enough and that's evident all over. Also small things like shadow on top of the head? Right now with the latest version I noticed that you actually lost some contrast that you had previously had, so it might be worth messing about with the colours a bit more.

I struggle to convey critique, so I might create an edit later after you've done another pass on this character.
Hope that helps.

As quick an edit as I can possibly make, I'm being rushed to play rocket league.

I saw this the first time round, thought I'd take some time to post.
Major things I want to point out with the latest iteration as quickly as possible. The character looks like he's going to topple over backwards. Lighting is all over the place, it might be worth reading a bit into light theory. Anatomically its still a bit odd compared even to the old one. Clothing doesn't seem separate to the person, they look like one entity, things like having clothing hanging or blowing in the wind can go a long way in make this read as more believable. The shadow on the chest makes no sense?

Hope that helps a bit, will clean up this post tomorrow.

So I don't really have the time to commit to any long term projects at the moment, so instead, I thought it might be nice to revisit an old mockup I made back in 2011. I'm a bit rusty as I don't do much art at all and haven't done much for a long time, so we'll see how this goes. Please bare with me 

I kinda want to use this thread to jot down my thoughts, inspirations, references and generally post any progress I make. So while I am looking for feedback, just know that initially I won't have anything to show, just thoughts. Anyway,

Here's the old Mockup

^{Looks pretty right?}
I know there are a lot of issues here, but I don't think it looks terrible. So here are a few issues I know about because of previous comments and what I've learnt over the years. So, Priority issues, characters didn't read well enough, it wasn't obvious that the character could interact with things and the mockup didn't illustrate well enough what the characters objectives where. The last point being the most important, I mean it looks like a game, but what do you actually do? I just made things back then and threw them into an image without to much thought about anything other than what the game might to look like. And now I think it might be fun to revisit this with a new perspective.

I'm not sure where people usually start when making a game, probably concept art. I'm probably skip the concept art part and just use references for inspiration, which I will post as I go. And I 'll start specifically with the main character, because, well that seems fun and motivation drives me at the moment 

Something to note, I'll be working at a higher resolution compared to the last mockup.

Here he is.

^Gus
I won't talk about the characters objective, mainly because I have no idea what that is yet, but thats all part of the journey I guess.
Things I do know.
-He's from the past.
-He's a mechanic.
-Red and blue colour scheme (might change).

References so far:
Apparently if you search mechanic you'll find red and blue to be a very common colour scheme.

Trucker is probably more accurate in what type of clothing I want him to wear. Maybe.

This is the last red for the character

I think I'll start doing some art now

Edit:
Okay, first pass on the character done. Will look at it again in the morning.

^{Gus 1.52}
I decided to keep him largely the same, keeping the trucker hat and white shirt, but changing the blue jeans for a mechanics overalls which are pulled down to his waist, also changed the read sneakers for black steel capped boots. Hopefully the overalls will add to making a more dynamic, interesting looking animation, and the heavy boots would also add more weight. I'm not going to put to much thought into it, because I'm likely to change this a lot 

I'm in.
