I'm creating a map for my ttrpg campaign and I'm really struggling with forests. I can never make them look good for some reason. I'm just doing a bunch of tests on forests and seeing what works for me. On the eastern side you can see some forests I have put down. Could I get some tips and suggestions on what i can do to make it look more natural? Thanks!
