It's mostly an improvised chord progression (and you obviously have a good ear for it!), with some melodic moments that feel more like harmonic accompaniments than parts of an actual melody. I think you should write a tune to go with this when you develop it. (Don't cheat and just do arpeggios!)
Thank you so much for the feedback! That's actually a reason why I really wanted to make a Orchestra version since I feel like the instruments in a Orchestra would really compliment each other. I rarely use a Arpeggiator unless I feel like it suits the song, in this case I don't feel like it would really fit with what I'm trying to achieve or present with this song.
This is an absolutely wonderful improvisation! I too happen to like anime, and I spend a fair amount of time watching it (at least when bingeing). Well played ^___^
