I can't believe I stayed up so late to do this, and I'm not even finished.
Ok, taking in account all advice given, here's a more solid-coloured version. But it takes a lot longer, so it's missing a lot of things, most notably the eyes. What do I do about the eyes? How do I colour it? It looks too complicated and I't bound to loss detail by covering the pencil lines.
I did my best with shading, but I think the clothing is too transparent again. It has a very different feel. Still not the same as Helena's style though... And the program I'm using only lets me use 5 layers. I'll be looking into GIMP for sure.
