Space Mural

So here's a few thumbnail paintings of what could be my cousins baby mural. I would have done more but I didn't have much paper that was appropriate for acrylic paint (wall paint). It was a fun project and I would love some feedback. I plan to revise the one chosen and add or take away what works and what doesn't. I can replace a planet or spaceship. I was also thinking it might be cute to have a boarder of the alphabet or numbers around the mural or somehow incorporate the baby's name somewhere. Since the actual mural will be larger then these I can also add more detail and objects!
