Please do. I haven't seen any criticism in any comments on this site (even if they are trying to be constructive)
I guess I'm not sure how things work round these parts yet...
The eye dose look good but still, in my opinion the only thing that matters is how you shaded it, I can google and or take a picture of my eye and to get the shapes. The shading is the hard part and I think you would benefit if you show that process.
