Wow! Those are all very nice. I would say that if you had to get rid of one, I would say #7 or #9 (the two sprites). They are not worse than the others, but they are the closest to each other, and you may want diversity. Just my opinion, though. As for order, it probably doesn't matter, since none of them look seasonal. (#5 might want to be in winter because of the winterly background, and #4 might be a good spring time one because they look like rabbits).

It may seem rather sudden to you, but I've decided I'd like to take over the world! (Laughs) Ahem! Anyway, to begin... Dr. Light! I'll be taking your precious robots!!" - in the beginning of Mega Man: Powered Up (Quote from Wikipedia)
