Have I head this before? :O
Hmm.. The beginning of the solo was a little dissonant for my taste, you landed some lines on some rather (IMO) weird notes (I'm no fan of +11 :P). Then it got better. The middle-part was nice, maybe a little bland (mashing thirds for example). The parts without drums were in y opinion the most tasteful ones. Some parts were kinda "look, I know the blues scale"-ish, while others were more in my taste :)
There's two things I think you should do; move away from A-minor ;). I've not heard everything you play, but of what I've heard, everything is A-minor. Second thing, I think you should try improvising on the chords a little more, not just play a fitting blues scale. For example, try sticking alot to the thirds and sevenths of whatever chord you're on. I think you would evolve as a musician if you did these two things.
