I just said that because I'm acostumated to deal with Zoo Tycoon 2 projects, it is not a free game (but a really good game) and all the stuff that other users did, you need permition to use it.
But well, anyways, as I said, you need to change the textures, try finding some in the internet, for example, on the elemental initiates, but lava texture on the fire one, and etc...
I think it would look good.
