Rachmaninoff-Etudes, No. 1 in B Minor

I'm taking a little twisty turn here, I'm gonna start to make Rachaninoff-inpired compositions in practice of being somewhat like him and learning new techniques in composing. This pieces are mainly a study for composition and mostly to myself. There was no excuse to making this piece so short, I was just lazy. Sorry.
Any tips would be appreciated :/

update: added a name
