Re: music art?
I'm actually really jivin the sketchyness. Colors look great, most are pretty intense and some are kind of dull for a little contrast.
And the ... "linework" is cool too. It's all pretty organic-feeling. None of th edges are perfectly straight so it helps take this very familiar shape that we know is very defined and geometric, almost, and gives it a more loose feel. MAYBE PLAY SOME BLUES MUSIC WHILE YOU MAKE IT EH? ER SOME SWEET JAM BANDZ.
Maybe do a shadow from the bottom? As if it was standing straight up... (shadows in the same segmented color format, complimentary to the colors on the guitar itself, so blues and blue-violets)
pwn pwn pwn you can live in my closet if you want.
