If you want to distinguish between the various town sizes you might want to add some more varied symbols for that...I see a horned thing, a boat, and a bunch of 2-hut things. Maybe add a 3-hutter and a one-hutter then you'd have 3 sizes...city, town, and village. Overall, I'd say it is not overloaded at all but maybe that comes from years of looking at hex maps So far so good.
