Hey Vicious Zen; welcome to the boards. Regarding the sprite tutorials, there's a wealth of knowledge in
this thread. Check out st0ven's site (
spriteart.com) especially; it's got a bunch of useful tutorials for beginners.
On to the sprite:
-I disagree with CAG regarding the color choice; there's nothing wrong with "normal" colors. That and there's nothing "normal" about green hair :-P Not that it's a bad thing, just not normal.
-The headphone cord (if that's what the white line across the torso is) needs more contrast. Consider making it white, or at least almost-white.
-The pants shadow color could stand to be darker; a bit more contrast there and on the shirt would help define the form a bit better.
-The hair is very flat at the moment; in fact the whole head is rather flat. Again, contrast will help you here, but you will need to add some shading to the hair.
-The outlines look ok, but some selective outlining might be a good idea; the outlines look a bit jagged in places, notable the front of the pants.
Overall, it's a good start, but the sprite does need some work. Good luck with this.
