Hello, I'm Herone!

This is my first digitally-made map that I'm actually proud of! I'm using GIMP software to create it.

I thought it would be a good idea to post what I have so far so all of you wise map makers can give me some constructive criticism. I really like what I've done, but it still looks very bland and I'm not sure how to make it pop.
