Jeremy, you REALLY should do some anatomy studies. Your pixel technique is amazing, but one thing that troubles me with most, if not all, of your pieces, is that the anatomy/base drawing are very, very, wrong. Here, look at this.
I understand that you might have been going for a stylized person instead of trying to get anatomy to be accurate, but even then, you have to be consistent. "Real" humans have each part of the arm 1,5 heads large, while his right arm is two heads long on the upper part, and one on the lower, and the left arm has one head on each part. Body and legs are around half the size a real person's should be, but that part could be just a stylistic choice, though it still looks a little weird.
This is awesome only thing i can point out is the middle chief (with the nikes) left arm looks kinda funny, besides that really well done!
This depicts the same man at three stages of life? Very cool, especially the lion headdress!
I laughed at the chief's Nikes, but they make his blades look weird. If sneakers are available, then the head honcho can surely acquire a gun instead of crude swords.
oooh i see what the lion is now! it was a little hard to make out because the shaman's arms are blended in with his outfit without too much distinction. but you totally rock those 13 colors better then i would.
It's a little hard to see that the shaman isn't just a pile of lion pelt at first, great work otherwise.
..Also, is the chief wearing Nikes? Damn.
Oh, also, the Chief's right hand is not actually holding the sword, the sword is just floating behind it. :P
