I noticed you saved it as a jpeg and for some reason jpeg tags dont appear clear for me. I agree about the over contrasted looking parts and also about the right side appearing really flat. I think the background could use some work aswell...especially if you want it to look like a vortex or portal or w/e. Then again this could all be because of the way the jpeg appears for me personally. I do like how you are starting to try and use clipping masks though. I think they would be more suited on the left side if you want to achieve the look as if he is coming from somewhere else.
