can you smell what the caricaturist is drawing?

if not, consider yourself fortunate, as it smells a lot like dwayne "the rock" johnson. i did this one for the monthly contest at wittygraphy. i was originally going to do just one of my usual pencil sketch-style thingies, but something about it just made me feel inspired to keep going with it. so i've been working on it all month, ten or fifteen minutes here, half an hour there... and there were several times when i started to feel like i had blown it, it wasn't working and i should just scrap it and start over. but i kept working it, and eventually got something i was quite happy with. except i'm not 100% committed to the background. i'm so bad at backgrounds! i'm wide open to suggestions on that.
