The reason is : I tried to make an abstract effect , i ublish this one week ago but i upgrade it cause i made just a part of a eye and actually i finish the work and joined all the parts with an abstract effect.
i'm working in the full version
I don't see any reason to split this too. Would look great without I think 
Any reason you splitted it in 4? I wanna see the whole piece! It look gorgeous!
@RedOne, What do you mean? A RIP or just Ref'd?...any link so we can see?
