I like it. A couple of thoughts. In the exposition I think you handled the second theme the best. The opening, I think, should be less careful, more reckless and aggressive. And then in the coda to the exposition I don't think you need to slow down quite as much; the music itself creates that feeling of reduced tension with still something brooding in the background. I hope you'll post a recording you are more happy with yourself. I expect it will be very good.
