I see what you mean.
The original colors in the CC3 drawing were softer, but they got "emphasized" by the GIMP effects that I used to give a tattered feel to the paper.
There is no actual background justification for the blue color on the montain.
I just saw the maps done by Sarah Wroot on the ProFantasy website and decided that I wanted to try the eponym style available for CC3.
But you are right to say that the blue and orange are now too distracting, so I lightened the colors in the CC3 drawing and imported it again to the GIMP (original post updated with modified drawing).
I think that the blue and orange are less dominant, with more of the paper texture showing through.
Thanks to both of you for pointing it for me!
