'Two of Us' for CrazyRiah

I finally got around to making this! This is for the BeatleFreaks Christmas exchange. My gift is for . This was her request:

Favourite Beatle: John Lennon
Favourite Song: Two of Us
Favourite Era: White Album

I...I couldn't figure out what I wanted to draw. Originally, I was going to draw a comic where John and Paul were going on a road trip, and Paul would not stop singing "Two of Us." But, I've had some pretty bad art block, and I couldn't draw anything. Then today, I started to watch Adventure Time and decided that I'd draw John and Yoko in that style. ~CrazyRiah, I hope you like it; it's very late and not very intricate, but I guess better late than never!

I need to learn how to draw shadows.
