Thanks for the comments jb, I added a scale and also put more contrast in the hills and mountains to pump them up. I will probably try to add a more cliff like feature to help show this feature of santorini. I've added a drop shadow on the text to help separate.

I'm a graphic design and do a lot of placement maps, but trying to expand my map making skills, this is such a great site for inspiration and the tutorials are really helpful. Santorini06-01.jpg
