Artist in the house..Can you guess this theme?

So a new development happened this year in preK. Keenan has become an artist. I say this not lightly as he daily is doing art projects for hours. On his special mommy day during spring break we went to the Frist museum. He didn't want to leave. 2.5 hours later (and not having lunch - which if you know my child you know is amazing that he wasn't complaining) - he still didn't want to leave. I had to drag him out of there. He then came home and two days later was drawing a picture he had seen there (Rembrandt) by memory. He does so much art that I don't know what to do with it. Just tonight he drew 12 pictures in one hour. See above. I started documenting it by taking pictures of the art as I just can't keep it all. I have to say how impressed I am with his imagination and skills daily. He does not get this from me - but most likely Aunt Molly and Grandma Susie who both have this art gene that I never received. At 5 he already draws better than I could even imagine. Ps....The theme on these pictures he knocked out - Star Wars!
