Looks good. I like what you've done.
For the drums, the only thing missing is the snare drum. Very shallow, metal shell with the spring (snare) across the bottom. It would sit right between Paul's knees. I could be wrong with this particular drummer, everyone has their own set up but a snare is pretty much the drum that a kit is built around.
Other than that, very cool. I also like musician sculpts, my only two scratch sculpts were both musicians.
I look forward to seeing some colour on these guys
