Fireflies

A second digital drawing I have ever done. I am now satisfied with the face, but I really need to work on creating backgrounds T^T I like the idea of fireflies... up close they are really disturbing looking bugs, but from afar, they are so magical...
But anyway first of all big thanks to for her amazing stock images which helped me a whole lot with the facial shading.
and second of all -big thanks to for her most awsome digital colouring tuorial ever. Plus her artwork gives me more than enough inspiration.

I would love to ask you all - what do you think? How could I improve it? and most of all - what should I paint next?
