Lazily coloured doodle.
I like drawing pics, hate colouring them.
Didn't think to draw what they were sitting on either. Let's use our imagination and say they're on a highly detailed moonlit roof top or something.
Anyway. Don't ask what that gadgey thing Don's holding is. I dunno, something technical that Don knows lots about and consequently is boring his brothers to tears as he excitedly tells them all about it.
I give Raph another 30 seconds before he looses it.
