Looks like a dececent start man.
When I was doing mine I concentarted on modeling before moving onto texturing, that way I could see the overall look of the guitar, as sometimes textures can be a bit of a "Quick fix" and mask any modeling problems.
Have ytou done the curve of the body? I would do this before modeling pickups etc as the curve will have a knock on effect to the position and thickness of the pickups etc.
Cheers for the comment on mine, good luck, looking forward to updates
