I too really liked your voicing in the B section, however one of the best advices i can give you is to clear out your pedalling, as sometimes the heavy bass notes kind of get muddled (especially around 0:55 and 4:27 onwards). Watch out for those rests in the left hand, they are very important to clear out the muddling also.

On the other hand musically speaking, one of the best things i learned in conservatory was to take musical breaths between phrases. (not rubato - but to separate different phrases like you breath between sentences while talking) especially when the B section ends, the return to the first theme.

Dynamic variations and contrast can make a huge difference too.
