Hey Pippin, good start to map making, here's just a few pointers from what I'm seeing.
- You put a lot of work on the trees, if I were you I'd switch more effort onto your buildings, trees should be more organic and less lined in while the buildings could use some.
- The water lines you have all over the sea should be a bit subtler and draw less of the eyes attention.
- And tone down the edge cracks a bit, it's a little crazy.
Keep up the good work!
