I have no idea why nobody commented thus far, but let me be the first to post here!
first of all congratulations for your very first work (I'm guesing that this is probably your first finished work, because it is quite mature, to be honest).
It's got a grasp of harmony and form, which is evident. It's small alright, but everything that could be said has been said in this tiny, one page work. It's playable with relative ease, and I'm also guessing that you worked on this with the piano (especially seeing the list of what you're currently studying). There's nothing wrong in following a few composers' works as long as you are aware that you are doing that, and I am hoping that you know you are following the footsteps of Rachmaninoff mostly.
Other than that I would like a few more dynamics in the score, but I think that this is more of a philosophical discussion (do we, composers, want to offer such precise instructions to the performer(s) or some should be left to their descretion?)
