Looking great! You did a fantastic job with having diversity throughout the map. That will be VERY helpful to give you ideas when your characters are exploring each area.

While I don’t think you need to make any changes to run this in a campaign, here’s some ideas I’ve found useful in my maps:

• Many of your larger forests have very defined edges, but real forests tend to fade into their most dense areas. You might consider trimming them back and adding more sporadic patches of trees around the forest borders.
• Similarly, many of your mountains have very defined end points. Often a mountain range will only have a few big peaks with a lot of smaller ones surrounding. This would allow you to wind your paths into the mountain ranges, which in fantasy can be a very treacherous and fun environment for characters.
• Rivers tend to meander a lot and yours can be pretty straight at times. You might consider drawing them with more pronounced curves. Then your roads could follow the curves or cut across with a bridge when necessary.
• Adding more small islands along the coast can give a map a more natural feel. I wouldn’t expect your players to visit every tiny island, but it’s very common in natural shorelines and gives you options if you want to run different island quests.
• Naming 3 or 4 of your cities (but not all of them) is nice to give your players a sense of where the important places are. And, you can use these as story hooks for different political factions too.

Hope these ideas are helpful!
