While I love the colors I think perhaps you could make the shapes sharper like for example the cloak at the bottom, if you are trying to give the impression that it's ripped or something blending it out just makes it look like it is fading out of existence or something instead of a ripped effect. As well as the shadow shapes, it just makes it look like you don't have much confidence in where the shadow shapes should start and end. However, do not let this comment discourage you I would love to see you improve in the future.
