Also for accuracy it isn't Took Hill, but actually Brandy Hall in Buck Land. "Took Hill" is south of Hobbiton and goes by the name of Tuckborough and/or The Great Smials, you may want to amend that small error. As for criticism on the visuals I can see an apparent line following along the base of the toporaphy where the grass texture and objects were worked up from. It would also be nice if all the base of trees blend into the ground rather then having defined bases. If you could clean that up it would help. As well the Brandy Hall has round windows as Tilt did say. Additionally with the level of detail I find some of the figures have I wish there was a way to add the same level details to the clouds around the Barrow Downs and the Brandywine. Also some of the figures are lack luster in compared to each other, I.E. Tom Bombadil and Goldberry. If you are looking for visual inspiration as well as the description within the novels. The Lord of the Rings has a MMORPG that is more true to the book then the movies and these characters as well as others are portrayed therein. I'm routing for you Rav's this month, I love Tolkien and what you are doing therefore wanna help you out as you go along. Only real negative thing I have to say I'm impartial to a version with quotes, but thats more of a personal preference. I'll keep popping in and out and try and make sure its accurate if you would like. Keep it up and hope you have the stamina.
Edit: Here's the two characters I referred to.
