Though mostly a matter of preference, this modpack replaces the current Asian monastery with one that has animated water. I think ES was originally going to do something like this, but scrapped it once they threw animated water terrain out the window. It fits in quite well with the game, and though not a major difference is a nice touch for those looking for a little more realism. The author should pitch the idea to the AOK:HD guys, now that they have added animated water.
As aforementioned, the graphic fits in quite well with the game and the author was kind enough to provide a screenshot on the filepage to illustrate the change before downloading it. It is a fine addition to a player's experience or a modder's toolbox. Minor deduction for the lack of a readme or comprehensive directions on how to use the modpack, as it comes in an .exe file, but nothing too major, as it can be deciphered by somebody with enough AOK technical know-how.
A great modpack, but I encourage the author to either update to include a readme or update the file description with a short list of directions. Assuming that is done, I would be happy to edit my review to a 5!
