If you're going to be doing more water features in Japan or Egypt you might want to look up some tips on reflections. I'm guessing they are generally going to be hard.
To be truthful with you, I'm completely fine with it being imperfect.
I don't think many people notice details like that, and if they do, that's fine by me.
Anyway, I appreciate you playing the game, hope to see you for the next release coming really soon.
