This illustration is great, but the book is pretty clear that she isn't pretty. I mean, it would be kind of silly if every single character was smoking hot. The whole theme of ASOIAF is gritty fantasy.
the other portraits you did from GoT are awesome but this one is like... amazing! i love the water dripping off of her, and the different perspective you got by drawing her with her chin tipped up like that. she looks gorgeous, and I love the colors as well... just, wow! you almost got a pastels effect, the way the colors are blended, but you did this on the computer right?
