I really like the main melody you've written, especially mm. 4-5. The first variation you go into works quite well I think, I think you should cut down on the arpeggios though. And then once again your lovely melody, I especially like the left hand in mm. 24. The crescendo at mm. 34 could be improved though, I think. There is not enough power in the tremolo in the left hand, I think you need to add more notes to the picture there. And the sf at mm. 37 would have benefited from a unison in my opinion, instead of a pale octave in the left hand. And it goes on, I don't like the variation there neither :P I think there are too many breaks. You have a constant change between climax and build up in mms. 40-43, I would have preferred one long build up instead. Then there's a good crossover to the melody, however I don't like the wide use of arpeggio, and then you go back to the main melody, which I gotta say is very enjoyable :)
Good work!
