Thanks for the advices pixie, using less colors on lands and more on the ocean seems a good idea i'll try that to represent various land use underwater.
That's funny Lingon how sometimes ideas are just in the air and we only catch them, i guess two cartographers are receptive to the same ideas
About the map i have reworked quite a bit underwater relief to give them a more central place on the map, as it is suposed to be the point of view of an underwater creature. I have done on purpose a strong relief effect on oceans to focus the attention on it, maybe it is a bit too strong?
