Since I do mostly covers and vector art now, I wanted something that would reflect that.
The result is this, my pony OC being a badass playing guitar in mid-air.
Vectoring the guitar alone took around 6 hours, and didn't trace a picture. I'm proud of that.
The guitar, strap, and even the cable are all my real life equipment, though I didn't have this guitar at the time I made the vector.
Couldn't think of a good background, so I used the powers of mathematics to produce... something.
