Artificial light in Erebor
Let me first say that I think the expanded Erebor looks grand. Love it. This has to do with the artificial light following you around in Erebor. I would suggest tuning it down a bit, and maybe add more torches, candlelights and other natural light-sources. I know this is a thing in Mirkwood as well as other areas in the game, and I've posted threads about it before, and it feels unnatural and slighty breaks immersion when you have lights casting shadows of you out of nowhere. So, tune the artificial surrounded light down a notch, if removing it altogether is not an option, and add more natural lights on walls, poles, floors and roofs for a more realistic lighting.
