Hi everyone. Yesterday had weird idea, to make an eye. Alone. On the wall or on the… cube. This is what i got after long evening. The cube is too smooth (subsurface edges…), but the whole thing is like “rendered imagination” 
That is, freaky … and Awesome!
But you need to texture the Iris and make the thing more specular.
Agree… eyeball texture i’ve done in few seconds. Must play with it and material later
[edit]
Found nice photo of Iris and made texture. Increased specular and ray-mirror values, but changes are not visible almost… This is another render:
c&c welcome
Hi,
I really love the concept of this one! 
I prefer the very first version of the eye, though: I think that the actual iris detracts to the picture overall, perhaps because it’s too much colorful and, thus, disturbing… Perhaps the “pixar-like-eye-ball” will be more suited to such a scene (http://www.blenderchar.org).
Perhaps should you also add a regular lamp (with low to mid intensity) to give slight saturation to the colours… The skin tone should benefit from this, I guess, as well ad the scene, globally.

I concur. That iris is just a little tool realistic - It’s like a real eye added to an abstract scene, rather than an abstract seen with realism applied. If you get what I mean…
if you think about ti, this could be used in the WC “all alone”
When I saw it, I immediately thought about the square shape being, instead, an ear.
Ok :] I’ve rendered another render, modified scene a bit, textures. Had not enough time to make complete look of idea that i saw. Anyway, thanks joguy923 for suggestion - i posted final render to WC :] You can find it at the end: https://blenderartists.org/forum/viewtopic.php?t=25231&start=60
[!] warning [!] I’m about getting anoying 
:
I still prefer the very first render!

Emm… %| Tried pixar-like eyes tutorial. With blender internal renderi it’s ok, but with yafray… things go in other way that I like. Maybe nevermind, this work is like matrialised idea, even unfinished.
/me silently closes yet another unfinished-scene folder.
Not because of my comments, I hope: I really love this one and I’ll be disappointed with you close this WIP just because I couldn’t have been more constructive with my comments… 
No no I really liked all of comments, they’re very valuable for project (especially those written by you, OlivS). But now it’s not the best time to work with blender… I have exams, work, and no time for weird projects of mine. But, someday I will open it again and make some better render. Happy blending
