The flow and play with realism in this picture is enormous. I find the head to be very near to reality, while the bizarre background texture tickles at my retina with a weird kind of overladen simplicity. Among that texture however I find these beautiful flowers that are so bright they might be mistaken for "negative space". Overall, the great play with the brightness of the positive space and the almost Japanese line (in quality) strongly remind me of the design of the God from "Mononoke-hime" by Hayao Miyazaki.
If you know what I mean It all looks like you did it with much devotion, but little effort.
