I really like this! I'm glad you decided to keep it in black and white. My suggestion would be to break up the forest texture of the two big forests a bit (you can see the tiling, just), have some little clearings which will make the tiling less obvious and the forest less dominating.Considering this is your first CC3 work, I have to say, I'm very impressed. You have a very good eye for what works (most people (like me) on their first time go crazy and throw in every symbol they can find)....or maybe it was just me!
