That main room is really cool. Nice caves :D
Just some of the corridors are a little bland and not easily recognized.
I wish there would have been more diversity in those (like in that waterfall room for example) Also they went a little far from the main room sometimes imho. Would be cooler if the main room had just a few smaller rooms around it, connected with shorter corridors to make navigation and learning easier.
Still nice style you got there :)

Next time you get into trouble with keeping it small, grab a piece of paper and plan it out a little before digging too far into earth :) It really helps.

Oh and by the way: Love that big weel construction, adds a lot "mine feeling"

very atmospheric map. only complaints would be a lack of texture variety, and the fact you never ran "remip" on it (look at the difference in geometry)

its a great map but because of the lack of texture variety i could not justify 5 stars. it deserves 4 and a half definently. like aardappel said it is very atmospheric and the lighting is just right.

This is one great map, and one of my favorites, but my only gripes are that the texture in the main mine room is too repetitive and the lighting in the same is not detailed enough (you have like four really bright lights--why?). For the texture, try something brown, like in that other mining complex one (curvedm?), or something that doesn't hurt the eyes.
