Just wondering what you guys would have done differently with this eye texture. It’s only practice from a tutorial so I probably won’t re-do it, but the colors look wrong to me. It looks okay from a distance, but close up I don’t know… Anyway, Photoshop noob alert.
The texture is ok but IMO a grown-up does not have such bright colorful eyes. The eyes of grown-ups are more grey and have not very much color - make the texture a little bit more blue and it fits perfectly for baby-eyes 
I personnally would’ve fuzzed out the outer edge just like you did with the inner one (fuzzy border between the black part and the blue part). And maybe use a darker shade of blue.
I just redid the tutorial to the letter and I think it turned out better. (Last time I chose my own colors.) I also added some blur around the outer edge like Borgleader said.
Also just fixed the blue one. No more tweaks though, because all my layers are combined now.
it looks good, LRJ, Perhaps you could add another layer, transparent with a little greyscale noise and a big radial blur over the top with an opacity of 30% or so just to break up the smoothness a little.
Have you seen my eyeball tutorial in the Finished Projects section?
