the eyes looks good but a few things i have to crit about them. well pretty much first of all, the vein's on the eyeball look too flat and makes it look abit wierd i reckon... and second of all, the background is really distracting kinda. coudnt you just put the eyeball's onto a grey phong plane? i think theyd make the render abit more appealing. anywho, thats my two-cents
