I think with the Spainish FF, you have to press while you have the advantage. In this game you waited too long for the shipments to come in, giving him time to get to fortress himself. I would attack no later than the second fortress shipment.
Don't send 2 towers against a Brit, he is not a threat at this point in the game. It's better to send 700 wood for stable/barracks and housing.
Apart from these strategic errors, I thought your economic management was pretty good in the early part of the game. However be aware of stockpiling wood. If this happens just take all your vills off wood, you can put them back on when required.
