To be honest, why choose between 2 cave types?
I mean, every cave is supposed to be different from the others.
Here is 2 "types" that could both fit inside the same cave.
Example: Narrow Cavern
Example: "open" cavern
So, All in all, what I wanna say is, just mix it up a little.
Also, DO NOT map a cave with 100% autoborder like I did in the second picture, it gets kinda shitty then
cba to try and map something good for a quick post xD
You shouldn't get to stuck on what other people say, take their advice, but don't get obsessed with them or you'll lose your own mapping style, which is bad
So, just map however you want, and then post the results.
Examples like those you just posted are, to me either extremely boring (1st pic) or WTF, Huge Mess! (2nd pic).
I think that if you want people to seriously vote for this, make 2 caves, exactly the same (at first) and then change them radically in some small ways to make them both unique.
Fix something like this, and I'll be sure to vote for the best looking one!
Because, for now, I will not..
Good Luck
Kind regards
