Cool! A couple things I noticed, I know you said it was only "inspired" by LotR, but;
1. The "Hobbit"'s head looks huge for the rest of the body.
2. If that is supposed to be gollum/schmeagol (spelling?), the skin should be more on the gray side, IMO.
Last, that mossy stuff never really looked right to me in dios/vignettes. I mean, it doesn't really resemble any 1:1 plants I've ever seen personally.
That said, I really like the rest of the groundwork, and the moving water looks great. Great figure painting too.
