Yeah, I know the grass texture is at top-left and that it's in grayscale, I just wasn't quite sure how to edit it. Since there's no pure grass tiles in LL, and being that I'm not an artist, I'll either need some help with that or someone else will have to do that. The only thing I can come up with is making the whole top just one color, and that looks bad.
Also, I'll fix the birch like Ninny posted above.
Last thing, I see a "Last Legacy" folder and a "Faithful" folder in Dropbox. Should I put the next version of my terrain.png in the Last Legacy folder? The last thing I submitted was to the Suggestions folder.
EDIT: Made stone, cobblestone, and mossy cobblestone texture. I'll provide an in-game screenshot if you guys want.

I also tried making a trapdoor out of the Large Wooden Window, but it was too ugly, so I scrapped it.
