i tend to prefer this faster and with a greater amount of crescendo at the beginning. almost like a huge hug from someone that you feel is very heartfelt and lifts you off your feet. yours is heartfelt, too,but because of the slower tempo it seems more languishing. suicidal or something (just at the beginning).
don't know why - but with beethoven i always hear optomism even in the darkest moments of some of the sonatas. but, everyone has a right to their own interpretations. and, i'm sure that you will find others who prefer it more serious and with precise intent.
there's a lot of staccato in the fast parts. i'd make it less staccato esp in the octaves.
you have good dexterity and momentum in most places. momentum, imo, is what it's all about. sweeping someone away with the moment.
