Structurally, theme 3 is more developed than the others. 
One aspect which makes the work little less typical is its harmony — a number of  dissonant suspensions and less common harmonic progressions, particularly in theme 3 (bars 13 ff). They are only  4-3 suspensions  but their effect is unusual because they occur in non-cadential situations.
