I am no art man so I cannot make constructive criticism, so here are comments and thoughts.

I very much like the red background. I could look at it for hours!
Oh no why is the moon falling apart come back moon
the way his arms are dripping is frightening!
Oh my the clock's hands HAVE hands what is going on this is cool!
Father Time (as I have dubbed him) has stolen the clock's battery and is flying away with it!
I can't really comment on the shadow people. I am not an expert in these matters.

I like it!
