Sorry can't rep you yet. This again is outstanding and the colors are really beautiful (minus the slightly dark issue noted). The color key, graphics, and text are so beautifully done.

The tight text leading and treatment of subheads gives this map such a historical flair, these little thing are what make a map an award winner. Great job on all the text treatment.

Couple comments.
Your longitude lines are touching the border?
Since you use caps on first letter of Horizontal Scale, should "D" in "Height and depth" be treated the same?
The spacing between headers and accompanying paragraphs vary a little too much?

Love the credit to the Hydrographer.

Looking forward to seeing the third in the series. Then you can rest on your laurels.
