I do a themed family portrait for my wife every Valentine's Day. Well, I was crazy busy with work and... I dunno. So I just finished it. My 2 year old, Penelope, looks and talks just like an Ewok, so that's why I went with the Return of the Jedi idea. And as for why I made my wife and I brother and sister, well, I wanted a lightsaber. When I saw this as a kid I sure wasn't wishing I could be Han Solo.
I also have 2 shirts up for voting. The first is at Threadless.
