Oh wow, I love this too! Your use of color is spectacular. I'm so sorry to read you're suffering from migraine. I can totally relate to that. Both my mother and I suffer from it too. It's really the worst thing ever from time to time.
This is awesome! I get migraines, too, so I can relate. That photo, though, wow! I love the texture/blend you used on the photo and that amazing, painty, textured cluster you made! The clouds are the perfect finishing touch.
