Euh. Could be worse. At least you have bonuses, unlike a certain other recent map (cough cough Afroeurasien).
Stuff that could be improved: -Territory shape -Adding larger bonuses, more than one territory -Maybe making it bigger/adding territories - the Vatican is small enough you could probably show individual blocks and major buildings -Balancing territory values - I understand this is a diplo map and thus based off how actually valuable territories are, the facts that: 1) all bonuses are 1 territory and 2) these bonuses are not evenly weighted makes it somewhat unbalanced. And to be honest, no one is going to play a diplo on this map so you may as well just get rid of the 1-territory bonuses.
