Something Interesting Methinks :P

My approach would be to combine all these ideas using that violin melody as a leitmotif and take it on even more of a journey through key changes and variations. Puts me in mind of dance macabre by saint saens, so maybe that will give you some inspiration

This is a great foundation to build upon, I don't have any specific suggestions but I'd love to see this expanded into a full track.

I like it! I'd say maybe you could add some kind of percussion (stomps and claps?) or maybe make it sound like a fanfare? Maybe we could collab if you want?
