I'll be honest I don't know a WHOLE lot about guitars either, but they work like most instruments by vibrating, the big open area in the middle amplifies the sound. This though looks like an electric guitar, which needs to be plugged into an amp to be heard, because they don't use the wood an hollow area to amplify the sound normally. Since it's all electronic ya don't have to worry much about the shape of the body at all (Except the strings of course) so this would work fine!
If you wanted to add some small details to improve functionality though, you could add a little nub at the end ( Usually what guitars will rest on, if propped up on the floor rather than a stand) and adjust the tuning keys so they have little knobs on the end and could be turned (Since that's how you tighten the strings as they stretch out) right now they just look like straight poles which would be very difficult to use ahaha, but really for the simplicity they look fine, it gives enough of an idea of what should be there if you chose not to touch it up : )
