Aspiring student attempts Rachmaninoff- Prelude in G# Minor

[arbyxarby]

Worked on this piece on and off for about 3 weeks in tangent with a Chopin nocturne. 14 years old and has been studying piano since the age of seven. I only really got into serious practicing about a year ago.

My hand posture is pretty bad. But I my sitting posture is pretty much perfect (back straight etc). Any tips?

I know it's kind of messy, I think I was high off of too much motrin.
