OP's Description:

This started out as a little sketch, then I decided to keep building on it, using a black Sharpie and a yellow oil pastel. Even though it was different from what I'm used to doing, I had quite a bit of fun drawing Optimus dancing. :)

This was inspired by Pharrell Williams' song, Happy. It has become one of my favorite songs, really because of the positive message. Here's a link to the music video if you haven't seen it.

That song can cheer just about anybody up! :)
