You guys are clearly enjoying yourselves and mesh well. Surely you're both talented classical pianists. Thank you for posting it.
That being said, it sounds like what happens when I sit at the piano and let my 3-year old niece play with me. Some banging, some chords; occasionally stumble onto something that works, but the ideas are fleeting.
What I think you should really do with this, is extract the best themes from these improvisations you post, and flesh them out further in a written composition. There's some good stuff here -- don't let it go to waste.
