First off, I would like to point out how beautiful the colors are and the stunning designs on the kimono are just breath-taking. Plus, the way the artist made the fan motion look as if she's really waving the fan is a wonderful touch to the picture.
In this piece, I can only point out a few flaws within the proportion of the face. The way the lips were placed doesn't so much as match up along with the way the direction she's looking. These kind of face poses are sometimes extremely difficult, but with practice and practice, it becomes easy. Also the head is partially too large...when drawing, it's a good idea to start with the basic shapes. In which case the head would be in the shape of a circle. You can then edit out however the hair design is.
I would also like to point out that the hair is amazing. I've always admired hair that was drawn this way. Overall, the picture is beautiful and really eye catching. Excellent work.
Just like the other critiquer said, the hair is absolutely amazing! The ornaments in her hair, however, don't seem to really match the piece. They seem sort of cut and paste. The colours in this are extraordinary though! I absolutely love them!
One thing you have to watch out for is shading. On the girls hair and face, the shading appears to come from the bottom left, but on the clothes and fan it seems to come from the top right.
The background also doesn't seem to match the piece. This may just be my personal opinion, but it looks more like a texture that you cut and paste on without putting any effort into, and it seems to be kind of random. Try making it more of a tangible background, like an actual place she could be at.
Her clothes are absolutely beautiful though! The folds and the pattern are amazing, and the colors are simply stunning! I really do love this piece!
