Not sure why, but the yellowish colors just take away from this picture. I am sure the figurine is that color, just that it isn't really interesting. The pixie dust is a good touch.
I like how you caught the dust flying in the air. I can see why you included the leafy vine in the background, but I find with it overlapping the model it cramps the composition. I may have moved the elf to the right some so there was a bit more space.
