I've been wanting to review this since I first saw it, but it'll take so long that I didn't previously have time! Anyway...
Although it's only one floor and doesn't have a lot of furniture, I really like it. The beams hanging from the ceiling are great, and the furniture that there is
is very nice. The walls, both inside and out, are a nice texture and color. I like dark tan because it means you can make roads and still have tan (I've gotta start calling that beige, 'cause that's what it really
is) buildings! I also love how the tree is carved out for the path, and how the roots hang off the side of the cliff, and the whole look of the tree itself.
The cliff and outside:
The cliff under the house is really good, but it kinda seems like there are a few sort of 'columns' there, and they make it look odd... although looking at the caves, maybe you wanted columns out there. The tall cliff above
the house really looks like an ancient curtain wall. I like the railing next to the path, very nice. The sort of scooped-out arch-y tower things at both ends of the bridge are great. They really look like ancient buildings that have been overgrown by rock (not that that could happen). The bridge itself is nice looking, and appropriately rickety. The waterfall behind it is very nice, I love the transparency, but the clear radar dishes at the bottom look weird. The stairs leading down to the river bank are wonderful, I like how you made them look older and more natural by covering the edges on some of them, and making them crooked, but they mainly stand out by being light grey, while a lot of the rest of the stone is dark. I also like the tree on the stairs. The bank is great, it really looks like a hill, and I like how the rock goes under the ground.
Inside the caves:
The main cave reminds me of what I picture Moria like when I'm reading FotR, but on a much smaller scale. The pillars and gallery are very nice, and I love all the tracks everywhere, they make it look like the people were very advanced miners. The end of the gallery looks a lot like a cave-in, and that's cool. The treasure room is very nice, I really like the stone chests and especially the wagon.
Overall this is a beautiful creation, and it's nice to see the vikings portrayed peaceably. The legend is great, and I really like the feel of the whole thing. I hope you continue this series (which I'm guessing you will). This is my favorite picture,
because even though the clarity isn't that good, I love the angle and the lighting. The only things I don't like are the cut-away corners, although if this is a series, you might've made those to link to more sections....
