Arnheim, I'm curious why you decided not to use the Undead rules and instead use the Empire Rules for a zombie army? Immune to Psychology and causing Fear are nice perks.
Also, if you have the means to do so, field larger units. Even in a 1000 point game Empire infantry is cheap enough to get up to 22 models.
Finally, your unit of "10 Zombiegunners 85 -Brace of Pistols" seems to be off. Is this suppose to be a pistolier unit, or is it a custom unit you have created for your army?
