I'll immediately admit I didn't know who 'Mac Miller' is - but this image immediately shouts 'rapper' and 'fun' to me. That's a style of music I only rarely listen to... So after looking, I searched, and found he is indeed a rapper, out of Pittsburg. Listening to a track now while writing this - your image seems to me to match the sound perfectly. I can't tell if the background actually depicts Pittsburg (been there only once), but it could be. (It would be fun if it actually is, but I don't think that really matters - 'could be' is enough.)
So for me, this image is a perfect match to his sound - excellent work!
