>>35818369A trick for the lines I have is to put the paintbrush tool slightly bigger than the lines, lower the opacity of it, and run then over with the brownish color the original lines are affected with. Makes them look slightly more natural, see
>>35804214 >>35802789I actually do it in reverse and use brown to do the lines then run over with black/grey but either should work.
This isn't perfect but I don't have a method to actually replicate them yet.
