Woo hoo more CC3 people! Welcome, Midgardsormr!
I think posting your first experiences and progress with CC3 is a great idea and will be of great use to others who might be interested in purchasing the program.
Quick question - is the map you are showing all CC3 output or is it just the landmass outline on top of a scanned image? If it's all CC3, I have some suggestions for you.
I've been using Campaign Cartographer in one form or another for about ten years and I love it. And CC3 is leaps and bounds 1000 times better than the first version I purchased.
