haha that was great! I actually improvised something that sounded similar to the first half of this, except mine was in a major key and I like yours better!!
Anyway, if you were just showing off your great skills and good ideas, then kudos to you and thanks for sharing. BUT, if you actually want feedback to turn it into a piece, this is my two cents, which you probably already know anyway.
There are great themes in here, so I guess now the next step would mean to move these ideas around, add or remove themes, and basically just edit it so that it goes from being a stream of thought to being an organized form of music. Your second part with the two pieces (chopsticks and I don't know the name of the other one) was very cute, but again, if you actually want to make a piece from the improvising, I suggest making that a different song, maybe called "Musical Embelishments"? lol.
So if you want to do anything with it, that's my comment, but if it was just for the heck of it, I loved it and I'd love to hear more! :laugh:
