Hi.
A couple of months ago I posted the beginning of this piece. However, I didn't had the courage to finish it.
But I started earlier this week again, but I'm stuck already.

I really don't know what to do with the robe, and I'm not sure about the lightsource either. Same as colors,...
I don't know how to make it smooth and make it look a little more realistic, although I think dithering would ruin it.



So, I really need some help here.
I'm not really good in English, so I don't think I'm going to understand the things you guys are going to say, but I'll try.
