i like the colors and the roundness of the curled fingers its a nice pallete within the hand, the hand itself has some structural issues especially the thumb, the red is a bit harsh too
Way to demonstrate that the best art is based on truth!
Pun explaining: Space has nipples, and the poke rocket is goin' to investigate!
I like the bg, the rest not so much, I guess i don't get the pun or whatever you're going for here.
Consider the fact that the hand is also a ship, and the shape will make sense(maybe).
And thanks for the compliments on colors!(Red is harsh indeed, but it works for me)
