Have you ever heard of the forums over at Concept Art? I would suggest checking them out. They have a very active artist community. You'd probably get more feedback over there.
They have artists of all skill levels, and even the ones who create super amazing work are willing to help out the beginners. It's so cool.
And yeah, I can't give you feedback because I don't know what I'm talking about, and you are much better than me.
However, I think you could push your work just that much farther in an environment with other artists and mentors.
