Thanks much guys!

@ Ilanthar : I like cities on this one, I used some symbols from some old Casssini's maps, a french cartographer

@ Vellum : nothing hard about the Ocean : 1 base layer (parchment type), then 1 texture layer (grunge texture) set at 70% opacity, some uses of brushes a bit and brushes again to do the outside of coastlines ( 2 layers with hard light and overlay blending modes set at low and medium opacity)
