I'm gonna agree with RP on what is a very nice looking map. Those simple changes you made really brought it out from what it was in the original image posted.

The compass certainly could use a bit of work though. I'd go with thinner lines and little to no large black oval.

Think of a stylized number 7, then keep that one,copy it, invert the copy horizontally, and then vertically...

that'd give ye a nice slim looking up and down arrow ((now, i don't mean for ye to actually use the number 7 to do this, use a stylized arrow and add a little length to the lines but... well... hopefully ye follow what i'm getting at... you've gone with a minimalist design and should let the min flow baby ))
