I love the warm color scheme and the emphasis of the contrasting butterfly. And the shattering head and halo(?) behind it really balances out the bright butterfly. The expression is so soft and subtle, but not dull like a neutral face. The perspective is wonderful and the skin is done exquisitely. The ribbons/ fabric flows so it doesn't look like a gentle breeze, but more fierce than that.
The light source confuses me a bit, but I like to look at it and think it's suggestion there's something else that exists in the shattering, fiery world that the painting is capturing.
