When I draw something complicated, I just go into "autopilot mode" and just focus on drawing the object (whether it's an instrument, vehicle, building, scenery, etc.) one line at a time. So it wasn't that bad drawing the sax--I've done a lot more complicated stuff in the past, and the hardest is definitely a background with buildings. But once I'm done with it and zoom out to see the full picture, it's so satisfying, definitely worth all the effort!!!
