It's cute, but here's where there's problems...
First, you're using tones that are just disappearing within the background. They don't really help much.
While you've made some nice AA on the moon, the man could use some improvement. Especially the head.
Dispite your use of many colors, alot of them are so close to one another that this image looks pretty flat. The different tones of orange for the head and hands for example get lost and it just looks like one solid color of orange.
So basicly, more contrast is needed.
