The theme is excellent!

I like.

 omg this is adorable ;w;

the best part is that you gave the ghost nipples

good but strange

THANKS for being YOU :D

Ghosts have nipples? XD

Loving the ghost on the left.

Good idea. Fairly nice in general. Also, he should say "BE-BEHIND YOU!" instead of using ..., it makes it a bit more convincing when you read it out, as "..." is really just a long pause and doesn't read as though he is trying to warn the ghost. I like the base they're standing on, really like the patterns and the colors you used in it. Shoulda put a bit more emotion into their faces? 

Great colors & too cute!

Tasty palette and style :)

 nice .. but i liked it more with those monochrome colors in the wip

Nice idea :) 

Very funny!

 Gostei bastante, só usou 16 cores? ficou muito legal =D =D =D=D 

GOOD WORK!

 OMG! Your style is FANTASTIC! Love it.

Haha, very cool idea. Although at first I thought the three lines to show that the yellow one was shocked was either a hat or a ponytail.

Hehe, those colors become more and more awesome the more people do with them!
