Listening to "Space Concierto". There's some great piano playing in there! The first full unison section after the piano intro reminds me a little of "Over the Edge" from JR's solo stuff. As has been said above, the mix is weird in some parts and there seems to be a lot of clipping. Some parts do sound pretty sloppy, but I feel most of that is actually coming from the drumming. I'm assuming you are playing the drum parts on keyboard, if so, it may be a good idea to play the different parts separately (drums together on one track, cymbals on another, percussion on another). That may help get things cleaner if you are not doing that. As a percussionist / drummer I think that's the biggest issue that I noticed. Definitely keep it up, you have some great ideas, will be checking out your other pieces too.
