>>37685785did some quick circling to help illustrate
1. This was what i meant by the brown, which you fixed in your revision.
2. when I said you were missing a cave corner i meant this part that i circled. I actually think you made the ledge worse by taking out the land behind it, instead of removing the whole chunk right beside it, just take out the little jump bits, it looked out of place, but keep the ledge itself.
3. You fixed the one side that had a 1 wide path, but the other end still has a 1 wide, try moving your cave area over by a block.
