I really want to love this tileset, but there are a couple of things that i find it hard to move past.
Mined out sections look too graphically 'busy'. All the beautiful work on other objects are lost in it. If plain old stone floors had a reduced tone, it would remove this very repetitive high contrasting feature and make the things that actually matter, stand out a bit more.
Smoothed tiles could also do with a reduction in the contrast somehow, as thousands of squares all over the floor also visually bury every other object nearby.
Also Workshops blend in with the background far too readily, i find it very hard to recognize where their boundaries are. this is probably exacerbated by the problem i explained above.
I understand its WIP, and i thank you for all your hard work. I very much look forward to following the progress of this tileset.
