I made a vector version of the picture of the owl and pussycat.
I've been wanting to make a Threadless design for ages, so I put this in the critiques section. People were really nice with their comments - they pointed out that the cat didn't have a tail before! It seemed so obvious once they pointed it out but I had been oblivious until then. So that was good. I'm not sure if it is worthy of actually submitting, but I enjoyed making the attempt. I think I will keep working at it and wait until I get a better idea.
