Haha, he looks so funny :D I like it ^^ Animation make this just funnier XD
Dont' worry about your English, native speakers can't even speak it. The sprite is very well done exept the the pants are apparently backlit while his upper body is frontlit.
This guy is great. I love what you have done with the anatomy. The linework stylizes your character in a sharp, interesting way, and I would really like to see more in this vein.
I will say that the head seems oddly detached. I think I understand what you were trying to do there, but perhaps the shift is too stark. Rather than creating a sharp contrast between the head and body, it just seems detached. Perhaps if you lowered the head on the neck a pixel or two, and did away with the black seam under the chin, it would blend better? Also, I do not quite understand your shading on the pants.
That aside, this guy is awesome. I hope that Pixel Joint sees a lot more work from you.
umm, this is pretty much the best thing i've seen in a while.
