The contrast between the simple geometric background pyramids and the swirling wizard spell is really great; the composition is perfectly balanced too, & it has a really wonderful outer-space feel. I'm not entirely sure about the roundness of the wizard's face but that's purely personal preference—and the face is doing a great job to visually tie in with the top of the wizard's staff, which is part of what's giving the entire piece the drama and crisp enjoyment that it has. :)
