Looks good. I would try to add a little weight to the legs, but that's more of a style thing.

Uh oh, Manupix gave me the frowny face 

Thanks for the feedback, guys! The background was something I rushed in the end and I think it really exaggerated all my problems, so I've removed it. I didn't really want to do some kind of crazy wide lens perspective, but I can see why the floor tiles gave that impression.

And while this is a "berserker" character, I'm actually going for more of a menacing, intimidating look, instead of a frenzied, energetic pose. Not so much evil super villain. Think more Luke Skywalker encountering Darth Vader in "Empire Strikes Back". Darth Vader isn't swinging his lightsaber like a madman, he's just standing there in the darkness, waiting. And then he flips out. So that's what I'm going for. Encountering Khârn the Betrayer in a dark hall.

Aside from the background I think the previous version had a problem with the legs and hips, perhaps.

Maybe this version is better?



Or did it make more sense to have the left leg forward, to balance the heavy chain axe? Fizzick, I don't know if the arms should be so much longer, because they're extending in opposite directions, not hanging right down. And if they were hanging right down, they shouldn't extend far past the crotch. Am I wrong?

Uh oh. I would keep the palette changes, but scrap those strange proportions. 
It is important that the parts of any creature move together, but here it looks like he's twisting his right arm backwards and his right leg forwards, which doesn't flow at all. I think the only issue with perspective was with the floor: instead of altering the marine to the floor, you should raise the floor's vanishing point to get a higher shot.

The reason I said lengthen the front arm was because its hand is currently at a horizontal level with the back hand. Now I see that maybe you should shorten the back forearm.

But really, for artistic purposes, I strongly suggest you make this guy less passive. It looks like he's posing for a catalog showcasing his armor and weapons. That's why I bent his knee, twisted his head and gave the eyes a glow. You could consider raising his plasma gun to up a the ready. But his breed of khorne knights never rest. If they're in a fight like it seems he is, they should always be looking for the next IG to crush.

I wonder what the plasma glow would look like green?

EDIT: sorry, I totally missed your paragraph on feel. I totally get that, though. Right now it seems a little flat footed, though. Earth fader was still pretty poised for action. Try bending the knees a little more and leaning him in?

Working on a new player base sprite for hoboquest. Needs to be really simple in form and animation so I can make tons and tons of weaponry and armor, ideas to make it look alright with as few frames as possible?
