Very cool idea, and a striking piece. If you don't mind my nitpicking though - I'm a guitar person - a couple of small details are off:
-You included the jack in red, but then the cable is in sort of a weird position, so it doesn't look like it's plugged into the jack. -The pickups aren't quite the right shape. Fender pickups like that aren't ovals. They're more like rectangles with half-circles on either end. - There should be a third pickup above the bridge. It looks weird without it.
The pickup could either be angled, like this: [link]
- If you're going to have the jack there, it seems like you should also have the knobs. Maybe that's just me.
-It could just be an optical illusion, but the neck looks a tad long. It's kind of venturing into shortscale P-bass territory. Again, maybe that's just me.
Maybe you were trying to make it look more like a generic guitar, but the shape is very clearly based on a Stratocaster. Anyone who knows even a little about guitars will recognize it, as I do, and to me it just looks a little wrong.
I really appreciate your effort in explaining to me the areas which need improvement. I'm planning to create a modified version of this image if I get a little time. And thanks a bunch for the compliments Sincerely Stanley
