This image looks unreal. Photoshopped? Or really an in-game screenshot?
Unfortunately it's not the original screenshot. There's a stronger glow than in-game and the contrast is higher.
One suggestion I would like to make is that the stone texture use smaller stones. It helps to make them look more fitted to the structure.
I'm not sure about that. I agree that on some walls the stone looks a little big (particularly the area), but generally I think it's a realistic size. Also, the textures are used for many different wall sizes (from castle walls to small shop walls) so the stone size is quite inconsistent, but something I can't do anything about without changing all of the building brfs to use more suitable stone textures. It's something I've thought about, and the only thing stopping me is it means that part of the mod (it would be an optional download) wouldn't be compatible with other mods, and that it would be a reasonably large download. However, in addition to choosing suitable stone sizes for specific structures, I'd also be able to use different stone textures. Currently I'm only using one texture to replace wall3 and stone_wall_2 (the main stone textures) as they are both used for every type of structure in the game. It would nice to be able to designate a texture specifically for castle walls, another for town houses, another for interiors etc.
Also, what lighting effects does M&B use in native?
I don't know much about lighting so don't know what it is called, but it would be a standard lighting. No modern effects such as bloom, HDR etc which obviously gives the game a bit of a flat feel to it. It's probably not as necessary in this game as it is in others since M&B is less about environment (when you're fighting it's among dozens to hundreds of others, and when you're not fighting the lighting doesn't really matter).
