Good to see you posted your first map.
My first question looking at your map: why do the mountains seem to float above the land? You have a shadow effect going on that creates that impression. It kinda messes up the whole map for me. There's soom good stuff in there, but I can't see past the mountains and weird shadow at the moment
- Try to use some sheet effects, they are very powerful. Your text is now blending into the terrain, with a nice glow effect you could counter that. Some of the symbols, like the towns, could also use an effect to make them pop out more.
- Try to keep the same color for lakes and rivers. Also, a lake should not have multiple exits.
If you haven't watched the CC3 video tutorials yet, you really should. They are great. They can be found in the tutorials section on the Profantasy website.
Don't be discouraged by my comment. Just keep getting at it until you get something you are satisfied with. It took me a long time to learn CC3 as well.
