Collaboration on whatever key this is in.

This evening I was improvising on the piano when I realised it might go better with some orchestral instruments. I can't read sheet music so I just used the piano roll. Also, sorry for the fact that is no introduction at all, I just didn't have any inspiration left at that point lol.

Haha! I enjoyed this against my initial impressions. You have some pleasant chord progressions; the rest, I’m not sure what I’d call but overall I think I understand your intentions. 
it would be challenging at best to collaborate on a work whose composer does not know with which key(s) to identify. Perhaps I’d give it a shot should you be clear as to what you want to achieve here.

@Markus Boyd Good evening! Thank you for your reply sir. 
 

to answer your question about what I wanted to achieve here, i dont know. It was a mashup of some previous improvisation themes. I am though currently working on my first real piece, I hope to finish it this week. And even better, i know in what key it is this time ;). I hope you will be kind enough to listen.
