I agree I need some more irregularity on the coast line. I'll make some updates for my next revision.

I did look at a few coastlines this morning. Part of how much irregularity may have a lot to do with the coast style. For example, if you look at Bar Harbor, Maine area you see more jagged areas. That is a very rocky coast with few beaches. If you go further south to Myrtle Beach, SC you have more sandy beaches and a smoother coast line.

Don't worry so much about sitting on hands. I am no artist and a rookie at computer drawn maps. The reason I posted so early in the process is to learn and fix stuff before I get so far that I have to start over. I am grateful for the feedback!
