Eye

First off, I've got to say that I was drawing, while trying to follow the steps in this link, which you might enjoy as well, I considered it quite helpful.
First drawing I've ever uploaded, woaw..

Especially the iris, is a thing that I really need to improve, and I'll (well, at least) probably try that later..
I know, that I got a lot of practice ahead of me, and I'd like your advice as well (=

Of course i need to progress myself, without following a guide/tutorial, I'll get there soon =^^=
