Hey good to see someone offering their music here!
I had to listen to crashtest3 a few times. I am assuming this is partly an improvisation? These are the time intervals I liked;
3:35-4:00 calm movement is nice. I think it would have been nice to hear the voice in the middle developed. The Eb (in the middle of the keyboard) repeated note forms the voice i feel, moving from there would have been beautiful to listen to after 3:55 onward develop it not just float away chromatically.
5:40-6:10 The trill is nice effect to make thigns sound light. the GbEbGb to AbDbAb chord in the upper range is nice, but it would be good to hear some few more notes fill in the change.
the faster louder movements, sound to me more like patterns running up and down so i dont have much opinion on it. There doesnt seem to me to be a focus in those parts, i just listen to the sound but i would never be able to hum it back to u
Hope your hands dont break smashing the piano like that ahaha, good work!
