Alright, starting off you can't truly just critique a part of something, though this is what I'll say. First, the animation is cycling way to quickly for a a run and it's rather hard already to even try and depict anything about the image. Though the character currently has no thighs, it just seems as it's two legs connecting to an oval base. Next, the right leg looks as if the character is simply kicking off the ground getting ready to win a sprinting race. So to have a continual looping of this will ruin the character pose no matter how great the detail, my suggestion would generally require an entire revampment of the animation. Starting out, your going to have to bring the lower right leg forward, and lift the ankle up by a margin or so, so that it doesn't seem as if the character is hyper-extending it with every step. Next, you should bring in the left leg a bit, because there are several issues with it's current stance as I issued above. Also you are going to have to redo the foot as a whole because it's highly awkward. Then in the matter of realism you are going to have to accent the natural anatomic muscle tone, that is assuming this is a human male. So instead of having flat sides try adding an oval or reclusive-type curve on either portions on both legs. Finally, there seems to be a static frame where it looks like your animation has a 3rd leg sprouting from it's right, I would suggest fixing this before doing any of the other changes.

If you have the time I'd appreciate if you could take out the frame that has a 3rd leg? I'm really lost in what you mean there.

When it comes to anatomy I have no deep knowledge of it, so it doesn't come as a surprise. But I'll have to go on a longer hunt for anatomical references. Or go out for a really long run.

the main flaw with this is that his knees don't bend, try running like that, im sure ud find it very hard. there needs to be a frame showing the contact to the floor with a fully stretched leg otherwise the landing part of this animation is simply missing...

yes as hawk mentioned there are some anatomy issues, but im sure working on the positions of the legs in each frame is more essential at this point because you just want to make a fluid, believable running character, id still make sure you keep the general proportions as best as you can whilst focusing on the animation but always remember you can go into further detail of fixing any anatomy issues later.

Comparing the two it's obvious what you mean, and I appreciate the edit. And yeah, keyframes should go before anatomy, but of course anatomy has a part in the keyframes too.

Thanks for the replies I'll be back in a few days when I think I have improved it.

I'm a bit bothered by how the background is strict on sideview, but the characters are slightly tilted    It seems a bit strange to me.

I'm not completely sure what you mean, but my two buttons on my stylus can be set to things like modifier, where I can choose alt, ctrl, etc, so I hold one button and touch the color I want to pick. And no need for moving it off tablet It's a wacom volito 2.

(wow, I'm slow at replying)

Rox: actually I had no idea that Swedes were that into "retro-style things". I don't know anyone else from my town that is actually. But that could have something to do with the fact that I live in Umeå and that I studied natural and social science (natur- och samhällsvetenskapliga programmet) in high school, not some aesthete program. Only thing that comes close is a local band that I like, called KPIST. They do video game-inspired music. I never spent much time with other artsy kids (from here that is, I have some friends in Stockholm) or anyone really into my interests for that matter either. I guess you find more people with those interests if you live in the south.

There used to be tons of demo parties to go to here in Sweden, but they seem to die out one after one, to make room for more gamer lan's

I don't have many friends that are that into demos and other retro things, but the parties used to be packed with people

I guess I'll add a boring story to the topic.

When I first started irc'ing in 96 or 97, I knew a guy who went by H3llSp4wn, and I thought 'man, numbers instead of letters, that's clever' (and I suppose at the time it sort of was), so I went by the nick Thi3f, which later became Tjuvas in places where Thi3f was taken, or not fitting, and then turned into Grapes, becuse uvas in spanish (Or something like it, I had a spanish speaking friend) means grapes. But when I got too well known, and wanted to be more anonymous, I used Colonel Mustard, and at the time, I didn't really connect the dots between Cluedo and Col. Mustard, it was something I noticed later

Merry christmas
