Hey dude i love the map, very cool, and very creative, If you have the chance do you think you could look at my maps and give me some feedback? I understand if you can't, but I would really appreciate it if you would, because as a fellow mapmaker I want to improve my maps as best possible .
Thanks for reading this.
TBH I don't have time to check out the maps in full atm(gotta go to uni in a bit), but from what I can see from the screenshots is this:
First of all, try to avoid using a texture pack in your screenshots. It can be confusing and misleading(no offense).
Secondly, I see that in some cases you suffer from brushstroke syndrome; use the erode tool, tnt it a bit, anything to make cavernous areas look less uniform. You won't regret it, once you see the final product.
Thirdly, from what I can see, your areas actually look pretty cool. They appear well thought out and aesthetically appealling. Good job on that.
