Map of the Mines - Isometric map

[Dr.Biotox]

I agree that it looks awfully good - certainly better than any of my ISO maps have turned out.

As far as suggestions, there are a couple over/under crossings where it looks like the "over" passage was intentional excavated uphill, straight over the lower passage, and then downhill again. While it's certainly possible that miners (or whoever is doing the excavation) would go to such lengths to avoid an intersection, it does cause me to question why. Given that ISO maps can be highly subjective, it's possible that my brain has just picked the wrong (i.e. not your) interpretation of these crossings - in which case I wouldn't bother making any changes. If you're feeling ambitious and want to change it - I'd recommend trying to keep both passages relatively straight when doing an over/under crossing - or if you have to curve a path, try curving the top passage "down and close" instead of "up and away" - I think it'll make the passage seem more like a legitimate curve than an "up and over" bridge of the lower passage.

Again - I think the map is wonderful as-is - it's just insane rabid perfectionists (like me) who can always find a nit to pick. (None of my maps are ever truly "finished" - I just stop working on them at some point... )

Thank's for your opinions. I try to explain my intentions with over and under crossing, and why I avoid intersections. I imagine that those who dig those passages wanted so much ore to dig in that way so they did it by digging and passing above and below the existing passages. I made ​​it to look that way. I do not know if it's just me, but something I'm not happy with shading, because it seems that it is not enough to show where the passage is, but maybe that's just me.
