Sorry for the late response! I've spent the past week moving 2,000 miles to the Windy City, so I've been chaotically discombobulated.

The music does partially come from improvisation. What happens is that I fiddle somewhat randomly, often while a little tipsy, happen upon a combination I like that fits with something else I've already done, remember it, refine it, and later write it. Excerpts of the music are put together like building blocks, mixing and matching and reworking until I get the sound I'm looking for in regards to the thematic ideas in my head. So it's a bit of both improvisation and calculation.

As for what's in the drawing, it's open to all potential interpretations!

I really want to do a refined recording of this, with a mic that's capable of properly capturing violin, getting undertones and doesn't hiccup on loud E string notes (that's not me screeching in the video, I swear!). Two days ago my new neighbor in the building knocked on my door while I was practicing, told me I'm really good and asked if he could listen a little. I played En route/Vibrations, to a more exacting standard than here, and he was most impressed by it and that it was an original composition. And I was glad to be working through my nerves in front of an audience a little more.
