I wish I could paint like you LOL Vibrant colours, you really blended them in well! I love the concept, and the background is superb! The hair is amazing, but I think it looks a bit too flat. You should make it fluffier LOL Great job, awesome stuff you got here!
Ah, I'm jealous of your watercolour skills! And the environment is so detailed!
My only critiques would be to use some reference for her anatomy, and perhaps use some less saturated colours for the background (the bridge and the grass/trees on the other side of the river). It's almost like all of the colours are trying to grab one's attention at once and it can be pretty confusing!
