Prelude in C# minor

Hi to all my fellow musicians.

Here's my latest piece for piano, that I spent the last two days writing.

Haven't quite finished the phrasing and dynamics yet.

I may possibly extend the work; but I'm not quite sure yet.

Hopefully I haven't accidentally stolen ideas from other pieces I've heard?

I know the initial chord progression of C#m to Am(maj7) came from a You Tube video; but can't remember which piece they were discussing. (Pretty sure it was from a film score; but can't remember which one.)

Anyway, hope you like it.

I wrote it for a concert in May. 

P.S. Can you guess which composer inspired me to write this?

(N.B. Revised scores will be posted below.)

Noticed a few hand clashes and enharmonic spelling errors today: so here's a revised draft.

Also made a tiny change in Bar 8 (left hand).

Hopefully better?

It's still a bit of a beast, with awkward hand-crossings; but I wrote it for someone with great technical skills! 

On playing this through myself tonight, I noticed a few further corrections and cautionaries that were required.

So here is my latest version of the score.
