that really looks like an authentic RTW strategy.
i think it wouldn't hold long against a human player/ real life archers.
archers shoudl be powerfull enough to obliterate one place in a line. and on Custom battle, a couple of things:
-lots of money spent on archers. money other players can spent on cav to outflank. or moere infantry to wash away your inf.
-it's very static, once the line is breached, there's not much to do other than break it up competely
-if the front infantry breaks ( the "__ ") your pretty mcuh screwed (with equal armies)

still very creative!
