hi franz, sounds like you're well on your way to developing a solid improvisational vocabulary. This fascinates me because the first scale I began improvising in was also G# minor. Anyway all I would say is keep expanding your vocabulary with new ways of playing scales...no need to limit yourslef to G# minor, either. I love some of the pedal-point ideas, very dark and creepy..anyway this shows a lot of promise I can hear a strong sense of melody in this piece. keep it up!
