Robot #2 in the Robot Parade

I showed the sketch yesterday - now here are a couple of finishes. I like the watercolor better. . .
but I tried another digital collage too - just for fun. I'm not sure about this one. The robot is too tall? The whole thing has a general sad/lonely feeling? I have another idea for a robot with a pull toy that I think will be more fun. Hopefully I'll get to that this afternoon.
