hey
Nice start, I will await further updates

.
editOkay... I might be jumping the gun here... but I'm not sure if I like the highlights on the bottom of the logs/roots. I think it looses some depth, and looks a bit pillowy? Hmm, well you probably should wait to see what others have to say about this.

I've done a quick edit to show you it without the highlights on the bottom of the logs/roots... hmm, not exactly sure about it though :\.
It also seems odd to me that the logs going downwards/vertical are lit the same as the logs going sideways/horizontal. Anyhows I'll just wait and see where it goes

.
and another...
->

Well I decided to do another edit, to try and fix the lighting a bit... although I think it still isn't so consistent or whatever :\. Ohh, and I probably screwed up your tiles in the process, as I just edited the thing as a whole. Well I done another, as I realised cause I took the downwards/vertical logs/roots down a shade, ther highlight was the same as the highlight of the things behind it, which ruined the perception of depth. So I took them things behind the logs/roots down a shade or so also. I hope that made sense, hehe
