Thanks to everyone for the comments.
Duncan11: Sure, I intend to. I've noticed that giving feedback to others instead of just posting own music is largely encouraged here, it's a really good thing.
Gardener: Thanks for the detailed comment, interesting thoughts. You're right that my approach was always very improvisational. I was usually kind of making it up as I went along, and a single track was done in about 1-2 hours. Hammond was the only track that had been somewhat pre-composed and not completely improvisational. I was first hesitant to release it at all, but some people have called it their favourite. I have been thinking about doing more stuff like this, and will probably take a bit less improvisational approach then.
