I just gave your piece a listen and read along. A short summary:
M. 7: This cadence does not really work. The i7sus4 is neither suspenseful nor consonant, just jarring. This is exacerbated through your bass movement, jumping from the minor seventh between g# and f# into a perfect eleventh. No style I know would use this movement to end a section.
MM. 9 ff.: Weird chromatic movement, ending abruptly again
MM. 13 ff.: s. above
MM. 17: An almost pleasant Cmaj7 on the second beat
MM. 21: Almost climactical, but Emin6 - G#minadd9 crashes it yet again
MM. 23 ff.: Off to an interesting start(nice rising figure topped with an apoggiatura), only to go wrong again
MM. 26 - 49(fin): This does not work at all
Now, not to leave without proper constructive criticism, I might add: I skimmed through other works of yours. In your Fantasy for Violin and Piano, you mostly manage to deliver a coherent(although very diatonic experience), leaving odd jumps aside for a second. Your Concerto Sketch does this even better, despite being just a sketch.
The beginning up to M. 7 works quite well. MM. 12-21 are also fine. Elsewhere, however, it is really disjointed. Especially the second half is just odd, the ending coming out of nowhere. What I think you fail at is subverting expectations: Instead, you introduce nice ideas and then go off the rails, leaving the listener behind.
Maybe you should try your hands at a smaller, simpler form. This piece does neither work as a sketch nor a fully-fledged work.
