B Minor Harmonica Improv with AUsher track

Here's a practice clip of something I'm developing in B minor 3rd position (on an A harp). Let me know what you think of the musical theme, it's complete improvisation, but I'm thinking of developing an arrangement out of it. Track can be found on Bandcamp here:

Instrument is a Hohner Crossover in A.
