Not a bad list, some less-typical things going on, props to that. My short list of things I'd change:
+ shield on exalted (for ranged fire or 1+ in combat)
- standard on foot marauders
- standard on horsemen
The marauder units are these tiny support / flanker units, in which case a standard on them is giving the enemy nearly double the points for killing them, and when flanking or baiting or killing warmachines, the standard doesn't matter anyway, as it won't be needed or the main unit in combat will have one anyway.
I think the above points might buy another warrior for that wee warrior block
- Salvage
