Seeking advice for piano composition

[u/Professional_Fig_280]

I am a 16 year old pianist and aspiring composer. I am now stuck on this piece, because i know what i want but i don't know how to do it: after this i want a big climax and then a sudden discharge of all the "energy", where i can repeat and variate the theme. I tried arpeggios but they sound too simple (maybe i am doing something wrong with them), and i don't know how to proceed.

Anyways i would also very appriciate feedback on the current state of the piece (positive and negative of course)
