Hey there, sorry for the late reply! There are currently no animated tiles in the set, however I will be updating and adding to this pack in the future so I'll keep that in mind. The tiles are all made to a 16x16 grid.
Thanks for your response! I purchased your pack a few days ago and started integrating it into my game. It looks really awesome! Here's a gif if you want to check it out: http://imgur.com/t/gaming/jRtdu
I'll probably tackle animating the water myself in a week or two.
