i heard the sonata it is a really good preformance, you have a good temperament an the right charcter, i think, but in some places there are tempo problems (the hardest thing :-)). maybe it is just the quoplity of the recording but you should make much more contrast between forte and piano, and make much bigger creschendo and diminuendos, i mean you making the dinamics but in many places you should do it much more in order that it will be more clear for the leastener.but very good! i enjoid you very much, really. btw how old are you?
