Space Dandy Themed Paitning

So in my Painting I did this final, and it's based off of some items from the Space Dandy Theme Song. 

I was going to add some colorful stars like the ones in the intro, but I ran out of time and It's due tomorrow. 

I also incorporated the silhouetted shapes of my rats. 

Any Critiques, I know the hand looks a little off, and I'm sorry D:
