Thanks all you guys !
Actually I'm usually working on more than 3-4 things at once Though this one was finished a few months ago. As for the colors on forests, the map wasn't intended to be colored. I just added the slight blue tone on the sea at the end to make the land pop up a bit.
Well I can speak about the client's choice for style As for the forests, I wouldn't call it "sickness". Styles need balance and consistency and this kind of map looks better with sparse forests in my opinion
