Looks really good, although at a quick glance the swamps look very much like lakes.
This is coming together quite nicely Seraphine, you've got a distinctive style here. BTW, are you building the setting online anywhere, such as the Obsidian Portal? I'm always curious to see what others are doing with their homebrew campaign settings.
Is anything else needed? Any rivers, lakes, or anything that are breaking any rules?
Even if I am correct, I would still advise you to follow your heart. This whole Cartographers Guild thing, it seems to me, is more about passion and skill and learning new techniques than it is about definitions and rules.

Can't see any 'rule breakers'. I really like your style. It's got a lot of personality to it. I'm a big fan of oversized icons on maps like these. I particularly like the way you've done the mountains. Great work and rep coming!
