I'm new here as well, so I can't say this with much certainty, but I feel like the dots would be nicer if they were fully within the road line, not overlapping onto the forests. I think that might be all there is to it.

Also, your linework is awesome - I saw all the progress you made and I really wish I knew how you did it. I can't get my lines to be smooth like that at all, I've really been struggling for the past few days with linework. Very well done!
