Wow this is amazing, if you don't mind me asking, how did you do your lighting? Is there a photoshop trick you'd be willing to share? It's fine if you don't want to tell me but it's so amazing I have to ask just in case. I watched your youtube tutorials and noticed that didn't show how you do your coloring so I'm asking here.
Seeing the preview image, you go, "Oh, pretty cool." Then, when you see the full image, it shows you the visual splendor that took you ryky some time to create. Very much so awesome. The soft light reflections are done with properly spellbinding results. This takes the eye work to yet another step up. Excellent, my friend.
It wasn't meant to, you make really incredible eyes. A tutorial really would be awesome, or some kind of walkthrough of your process. It's a lot to ask though, so if you don't really want to then I wouldn't be surprised
