a good starting for first movement
but as a listener (my harmony knowledge is very limited) i think the feeling you want to give is missing,
passion, love,hate, hunger... i dont know what's in your mind ;) ( i quess its romance but its my perception)
the intro is sounds good..until 18th measure it goes well
i like the change and mood in 30-36 measures
and my favorite part is outro ( the last 4 measures)
anyway
these are my ideas as a listener i hope they help
