A decent first attempt, but your entire left flank is underdefended. Of all the sieges I played today, this cost me the second-most men, but the outcome was never in question. It's just too easy to get inside the outer wall. Horribly inept engineers (under 40% hits - the guys were more wild than a knuckleballer on a bad day) on two of my trebuchets forced me to lose more men than I thought I would when I prepared for my final assault. I think you can tweak this one a tad and make it more difficult.
