It was pretty entertaining.
As it was pointed out already the animation could use a bit more work. We could see some animation problem around Cait neckline while she was jiggling. ;)
I don't know why people are complaining about the legs. They seems fine to me they compliment your character design well.
Also I don't understand the big deal is with people being outrage so much with the ''sexual'' content in this video. Heck I kinda expect it giving it a league of legend PARODY and most female characters in this game all wear scantily clad outfit. Whether it speak well or bad of the game itself is irrelevant to this video...
Also very important, if you borrow content always credit the creator in your video or in the Author Comments at the very least.
Good Flash overall, the message is true, looking forward to your future content.
