you got about the forests
just one thing that i saw, honestly dunno if it cares, but for my eyes in other maps not looks great. Your background paper have some irregularities in the border ( ofc coz ia a old Paper) but the drawed map dont have. i believe that when you draw in a cropped paper, the lines will get some curves coz of the irregularities of the paper. That is why i am still not prepared to use this types of borders. Check some " vorropohaiah" maps, he have some with this types of borders fitting very nice.
