Thanks for the feedback, everyone! I changed a few things, from the butterfly to the eyes that were too dark for a personification of spring. I also went back to the original coloring I had, which was frendlier and a little rose-tinted. This is the image I finally submitted.
I've redone this ([link]
) completely because I want to submit it to a contest and it wasn't nearly large enough, so I repainted it from scratch.
I'm much happier with this than with the original version, but I'd like to make it the best piece it can be, and for that I need feedback on what I can improve. So please, go ahead and tear it apart!
