This looks amazing!
I saw your post on Reddit and had to immediately download this pack to check it out myself. You know what caught my eye? The texture that you used for the fireplace -- the smooth granite.
It looks wonderful and I haven't seen anyone else do something so novel for this particular texture.
From what I've seen so far, everything is very consistent. The colors aren't too bright and oversaturated so there's a nice touch of "realism" to it without being super grim which I like very much! Overall, it just seems like a well done pack.
Keep up the great work!
