It's a guitar. In 3D. I guess it looks okay, but the "body" of the guitar is only black and very unintersting. It could use more art in the combination, also were does the video games-part come in?

Do you have any wireframes of the model to show? Also, what 3D software do you use?

Modelling in 3D isn't merely a video games-related "thing". I think this serves more as an illustration than a piece of art (art is subjective, I know - but I just see a guitar and merely a guitar doesn't strike me as anything thought-provoking/evoking.)
But yes, as a 3D-rendering of a musical instrument, it looks good. Maybe you could make something interesting out of it? (If you only wish was to make a 3d-rendering of a musical instrument, you have succeded - but as you mentioned art, I felt as if you were trying to create... Something... More.)
A side-note: When I think of art, video games and music I think of Metroid Metal. Especially the logo of the NES-era Samus Aran holding a guitar, for me it is possibly the purest combination of those three. Especially since Super Metroid is probably the best piece of art ever made for the SNES.
