I quite like this piece of art! It's very pretty, I love the design and the shiny optical effects. One main critique on this is proportions-related - the fairy's eyes and nose seem to be a little high up on her face, making it look sort of weird and stretched out. The lack of the end of the nose initially confused me as well. Also, I get the type of style you're likely going for (something along the lines of "adult cartoon"), but in my personal opinion, that waist being so skinny in comparison to her bust and thighs looks kind of weird and produces a kind of lumpy shape that I find to be too overexaggerated to be sexy. You can fix those things in your next art piece very easily, though. Overall nice job.
