Would it be too distracting to have the golden studs on his barbarian boxer move to indicate that he's twisting his hips while running? Otherwise it kind of looks like a He-Man doll where the legs are disconnected from the hip joints. It's really hard to do this detailed animation with 4 colors and I notice my eyes are struggling a bit to understand which arm is going back and forth at any given moment, because they're exactly the same color.

Thanks, cels.

Yeah, I'm thinking about doing just that... And the buckle thing should show up too when he's showing more of his chest..? Hmm, I don't know. But I'll try that and we'll see.
(edit: It was the opposite of that. )

I still have to do more adjustments as I feel it looks too different from the other animations. I might simplify that even more.
And maybe not make him move his arms and legs as much. And also I'm considering removing those boot straps (?), they're giving me a lot of trouble.

I'll add in your changes! Thank you!

PS: Climbing looks good, I think? I don't know. I can't really tell. I can be of more use if you're animating a spinning wheel kick or something. 

A Kick is going to happen, just not a spinning one. xD

Perhaps I should remove his left arm and make it so that he's using both arms when grabbing and pulling himself up...

While I don't do that, though:

So by now you guys should know that when I say "one last edit" what I'm actually saying is that I will keep on editing indefinitely.

No, I'm kidding, but I did find a couple more "solutions" for that hand (not that anybody asked for it in the first place, but still):

And the right hand...



Man, this palette has been really fun to work with.

Sure. Crouching / picking up the sword to save the princess.

Crap. Of course I should use that as a reference! Dumb me...

Princess though, huh? Hmm...

Messed around a little bit. Tried to do some cleaning, and added a bit more contrast here and there.
Overall I think it could get some darker shadows. Occlusion shadows, in particular.



You will notice I tried to reinforce the bones of the ribcage (which I am very fond of...) but I don't know if it fits the style.
