Very enjoyable; certainly good work for one night!
I think it would help your music immensely if you weaned yourself off Alberti bass, and found more original ways of keeping the movement going. (the rest of your style is very original, why not the accompaniment figures too?)
Two small details: your dynamics are too excessive (on the loud scale of things).
You use forte for passage that need to be played piano (and which come across that way) - and you use ffff!
An ffff orchestra would sink a battleship - you need to scale things down. ff is a sensible upper limit (especially for chamber music), and for that special 'battleship' moment, you can use fff. Then all the pp signs etc. make more sense.
The other thing: perhaps a result of hasty work, but you had a D flat, then a D natural moving in an upwards scale at one point... better to rewrite this as C # and D natural. Fewer accidentals, and makes more sense in your upwards-leading passage which was in C at the time, I think.
Other than those points, rather enjoyable.
