Thank you for all your comments. It is what makes putting these AAR:s together worthwile.
The swedes should have used their cavalry with support from the infantry and not on their own. That cost them the victory. I think the swedish commander's beer intake might have had something to do with the rash decisions...
The ruleset (I call it "1521" (the year of the Swedish war of liberation)) is fast paced and made for large battles fielding 500+ figures like this one. It was the first playtest and I would say it worked out well. Apart from setting the table, the actual playtime was only three hours, which is my aim (Most players are tired family men with time as the most precious asset).
I have made some modifications for the next round, tweaking some weapons, movement rates and simplifying morale and unit cohesion rules.
