Hum, I tried your suggestions (I think). Is it better? I fear the land effect might be too strong an and the outline too pixellated... or that's just me?

Btw, labelling can be hell... my condolences. Did you came up with all names or do you had them already? Just out of interest.
Hopefully, it's a world map (so, not so many mountains/rivers/details names...). I had to find the names and it was a long process since I had to develop my conlang dictionary in the same time. I think I've found the most part of the labels for this map, though.
