What I liked:
-Most of all, the lettering. Is that a font, or did you letter it yourself? Either way, it looks great.
-The little inset pictures - nice touch.
-The tufts of grass that help fill up what would otherwise be empty glaring space, without being too crowded.

What I didn't like:
-The broken coastal wave lines: they distract too much from the land in my opinion.
...and I guess that's it.

Can't rep you yet, so have a like and rating instead.
