Hmm I'm not sure, I want to like it but it does seem v confusing.

Just one other thing: this is going to sound v geeky and I'm probably completely wrong but aren't the phosphates and sugars the other way round?! Or I might just be getting them confused!

This maps a great idea! I like the way you've tried to keep the seas in keeping with the old map theme by making them quite neutral, sea-esque colours.

I don't understand Johloh's comment, surely if their all blue there won't be enough differences between them? Brown and green seem sea-like ...
