Decent eyeball
eyeballs are always pretty cool, i love this one nice colors infact you useing alot of lighting colors too, and with the black backround that really brings out the lighting effects on this one, i especially like the use pf purple under the eye, the actual white portion of the eyeball was good shading aswell, so this whole piece had alot of "RICH" colors and good shading, so as for making this better, maybe some design in the backround, still keeping the black but with some sorta design to it. anyways nice work.
~~THINGS TO IMPROVE ON~~
So as mentioned as above the backround, some design in the backround, still keeping the black but with some sorta design to it.
