This is a drawing about a saxophone

This is a sketch from a couple weekends ago. My friends Sarah & Tara were performing at Freddy’s Bar & Backroom, and the band that followed them was
Elijah Shiffer And The Robber Crabs. The sax player had a sort of steam punk-looking alto sax— it had a machine-like patina not generally associated with such an instrument. .

I began to draw it, but with so much detail amid all the movement, it was difficult to pin down. Anyway, I quite like this sketch, even unfinished.
