Yes, you need to change the font. It is too cartoonish to fit the sat-photo style of the map. (It is also so fat that I don't think I'd use it for a map it actually fit, either. It covers too much of the terrain underneath.) Otherwise, I think it passes inspection. Note that Vumhine is going to have to be quite moist to support those miles-wide rivers, but given the Zeresian Jungles, that looks to be your plan.
