Let's see, a few nitty gritty things.
I kind of don't like the little spider web looking thing in the top right corner. Is there any way you can remove that and keep the green behind it? Or, make it thinner and flatten it into the background a little more, rather than have it sticking out?
I also feel like the cape is a little too red compared to the rest of the image as a whole, but that is ignorable.
Everything else, I like. Good job!
