I think this is cool, definately not one of your best. I think you should do more stuff with the fairys in crazy positions, they're supposed to be mischievious and magical after all! Some funky, u believable poses would be amazing!
Confusing - i always thought she was sitting on a branch rather than on a root. v confusing! Like the purple. its unexpected but in a good way. maybe i would have been a bit more sloppy with the paints on the leaf as that is one of the beauties of watercolour, and possibly incorporated some of the colours of the autumn into the sky and visa-versa sky-wood etc. Just suggestions but it really is lovely and shouldn't be in scraps but in your gallery.
