I don't have the custom light rays (Couldn't find them through many google searches), so I can't create that one... and I added the fog after. Forgot to add it before I took the screenshot xD
The tileset only has one variation in vegetation and stuff like that. I have one mushroom and only two flowers to add. I'll work on it again and post a new version in an edit.
I hope this was the right fog graphic you meant.
I got really, really annoyed that the tilesets only had one variation of flowers and whatnot.
So I made, which I'm still making more, a little character sheet of flowers and whatnot. I don't know about other forests, but Daniel Boone's Nation Forest down here, has mushrooms as big as my head around almost everywhere! Also, many different trees, scrubs and bushes. Plus different grasses...
Well, I hope this one is at least better than the last xD
