Wassup. I am another mapmaker/fan of yours, and I have some things to say about your maps:
First is that Missile War = Pro Map, but needs a 0.58, as the winning strategy is rush, and there is no real anti rush defence. An anti rush defence needs to be implemented, otherwise it is good.
Second is that Naval Battle = Pro Map, but draws on too long, due to the spanish and british ships getting too strong. Piracy is hard, in many ways, which is expected but the one that really bites me hard is that it is too hard to get around as a pirate, also a general increase in hp would be good across all ships. Just a minor one, like 10-20% increase in base hp. Another mode could be a quick start, where you start with 10k gold and empires/pirates have upgraded a bit.
If you ever want help with anything I am good with GUI, but I don't do jass. (I can, but I am really poor at it.)
Hope the critizism helps.
