Eh, Not really my thing. Out of all of them #16 seems to be one the best drawn and colored ones though. #7/15 is an interesting pose, but the line work could be cleaner. #4 is alright, and #12 has some nice sketch appeal.
I love Rayman games... and it is really good than at least we can see than some people take their time for do sexy and erotic pics of the characters...
