I'm sorry, I don't suppose I was clear on what I meant when I said that the three doors together looked odd... I was speaking specifically about the three doorjambs that blocked in a one tile three way piece, not anything else. You didn't need to extend the hallway that lead to in_velothismall_room_02, which, after the extension you put on it, looks out of place compared to the compactedness of the tomb.
On that note, I think you added two too many hall pieces that leads to the room with the fresco. Another contradiction to the nice, compact feel that it had before. I'd say, get rid of two of those hall pieces, and the doorway to the room.
And I still think there's too many lights here. Take a look at other tombs, and take special note of how dark they tend to be. A few lights for large rooms, one for a hallway, and that's about it...
The more I look at them, the more I don't like the correctly sized (x1.00) urns between the altars. They just seem kinda out of place, for some reason.
Also, the "dark" lights, I feel are unnecessary. Too many of them... The place should look dark even without them, but if you want this place to be extra dark, a few would be good, but 8 is overkill, IMO.
On a final note, don't be afraid to play with the architecture more. You've got some halls, some rooms, altars, urns, and a fresco. Don't forget about ashpits, platforms, stairs, vaulted ceiling hallway pieces (the hallway pieces of in_velothilarge_*, specifically), and even a temple shrine or two that you could use.
I couldn't find much to comment on about the exterior... but only because you didn't do much to it. The vertex shading is better (though now that its got a larger radius under the trees, I would surmise that your setting is too dark), and a single bog is a start, but nothing special. So, I assume that you're more interested in interiors anyways.
Keep at it.
