Out of all the iamges you thumbsthis one caught my attention the most.
The coloring is beautiful and soft, very smooth. It has that 'almost' real look to it that a lot of people strive for. ^^ Your face seems a bit flat compared to the rest of the body though with the line work. I think it's the nose, it just doesn't suit the image at all.
Oh wow! great job theres nothing I can critique here! The colors look very very smooth and she looks wonderful. And The dragon was a nice touch. it makes the backround have something with out going overboard! You shall get a fave!
