wow... this looks awesome, reminds me of LOTR's hobbit houses. Also I'm pretty sure I've seen something very similar in some game, but I can't remember where exactly. Composition wise I think it might have been interesting if it was turned 90 degrees. That one green branch in front of it is a bit distracting, and in my opinion isn't really adding anything to the picture.
But I really like the teapot with the white fungi and moss growing on it, not something you see every day.
Well, I'm a game developer, soo ... just kidding I'm indeed one, but I neither made a game featuring it nor know one. Rotating it would really make it look a hobbit house I agree on the branch, good find!
The white "fungi" is in fact also part of the moss. The teapot is hanging in a glass house of a dear gamedeveloper friend of mine - and yes, it really is something amazingly unique!
Sorry for my late response. I tried to remember where I saw it, but the closest I can think of are Samorost and Botanicula, I haven't played either of those, but for all I know it might exist in there somewhere. They don't looks exactly like the picture, but I think the mood is similar.
