Pathfinder Map Pack: "Army Camp" [RPG]

I busted out Pathfinder Map Pack: Army Camp for a game last week.  Although I really like the concept, I think the execution is lacking.  The 18 5"x8" tiles are attractive and detailed, but there's too much repetition and not enough variety.  Eight of the tiles are tents, and although it is an army camp, that may be too many for a set like this (and the tents look more circus than military).  Four of the tiles are siege weapons (a cannon, two catapults, and a ballista).  Four of the tiles are for a palisade made of sharpened logs, but that's not enough tiles to actually encircle anything.  One alternative would have been to leave off the palisade, while another would have been to have edges of some of the other tiles contain parts of the palisade.  Neither option is ideal, but the half-measure here just doesn't work so well.  The last couple of tiles are an outdoor mess and a supply cache, and both are fine.  I think what would have been nice is a set of tiles that, if desired, could be used to build one complete small army camp or (with multiple sets) a larger camp.  Although the individual elements of this set are fine, they don't work so well as a cohesive whole.
