Thoughts on my map?

This is one of many maps I've made for FF6. I made this one to look like a treasure map, and was wondering if anyone has any comments or criticisms to make it better. I'm already working on fixing the Blackjack in the bottom right, and have plans to fix the readability of the text when there is land behind it. Oh and there will be a version with a legend on the side and numbers instead of the x's, so no need to mention that as well.

When finished I will release the .psd so anyone who wants to can move things around, change the opacity on the items, etc. Oh, and the .psd is 4200x2800, so it should stand the test of time compared to the other ones I downloaded from the internet.
