Looks so classic. I love pixel work and so your getting full stars.

The moon's like: "Come at meh, bro!"

lol I love both games

This is pretty good, but there are a few things holding it back. The first thing is that you have two tones of highlight, but only one tone of shadow. This is a bit jarring and leaves more to be desired for the piece. If you decide to go back and visit this piece, try to apply five tones of shading per color throughout the drawing. It will be a lot stronger if you do.

This would be a fun idea for a modification! :D
