Oh man. We found out what was causing the internet here to break for fifteen minutes after about a minute of working!

Done before reading the last two posts, so no changes based on those incorporated there. Also, hehe, the arms in mine are actually a lot different from the linearts . Personally, I'll like 'em, but I'll try making more real ones, to see how it looks .
For now: I'm really unsure about the end of the tail, how's it look to you guys?

Great work on the dinosaur, I have seen it as your avatar at tigersauce. I still have a few comments about what i don't like on the current iteration: the legs. Those metallic legs not only follow an slightly different perspective from the dinosaur, I feel that the size and pose of them wouldn't hold/balance the weight of the dinosaur quite well, and that there is nothing that describes how the mettalic leg is attached. Below is an subtle edit somewhat addressing those issues I perceive on it:



I made the "frontal face" of the legs broader, the angle of the knee bending somewhat more pronunciated (I would guess a t-rex would "crouch" a little and stretch the neck when performing a sort of warcry), as well as slightly more rounded the sides; the perspective on them is still off . I also added a stitched plate on the hips/waist that would probably hold the interface between circuitry and neurons.

I hope it is somewhat helpful my comment.

Again, great work.

Don't ask the reasoning behind it, I just felt like drawing it, despite the whole concept being like an oxymoron.  I really want some critiques on this one, though.


so far:

I really want to pull a semi-realistic reflective metal texture on the armor, but my mind fails to find a way to pull it off somewhat credibly; everytime I tend to add it, I just end up doing an incredibly mess that shows even less volume in the shape as well. Certainly adding/hacking up a backlight source doesn't fix that issue.

I really love these, specially the fatc that the infected bomb becomes and a tank, hehe.

I think the dude's forearms are a little too thin, judging by his head/torso proportions. If only they could be half a pixel wider.

It looks way too much like LoZ: Minish Cap. I'm sorry I cannot be any more constructive, I mean, your skills are good and all, but your style seems almost like a xerox copy to me.
