I think the mushrooms are about ready now. Basically, I made 3 different types and mapped them all to one set of 512x512 textures. One limitation that I realized later on is that it's difficult to get per-mushroom texture variations when all 3 of them are on one texture sheet. Since they're fairly small, I'll leave them as-is for now. I may look into adding more variations later though.
Now it's time to start on the turtle. I haven't modeled any animals before, so I think this will be a great new challenge. Rigging it will also be fun, and it should add some nice extra life and movement to the scene.
