No problem. tbh I really hate cave mapping xD! I see what you mean with the stone placement. Space I really struggled with filling so I'll probably make it a fair bit smaller. because that just looks Like "Hey giant terracotta Army of policemen in a cave"
I'll get to work on it when I have the motivation. xD
Uhm I'd say its a good start.
but I have the problem with the stone placement and that part where you go up the stairs.
The stone placement seems just throwed on there without any purpose (Stones should be place either to be a labyrinth or to look nice, which these dont, they just seem like obstacles that make kinda no sense).
And the part where you go on the stairs seems like the stones are just throwed there too.
Try to avoid big spaces if you dont know what to map there. Its enough if you make 3 tile passages and make them look nice while played through them, then making big passages in which you just try to fill the space.
