Ok so I had to proxy most of this army, but I made it work. Here goes:

warrior priest GW HA barded warhorse. Vanhoorstmann's speculum, ench shield

warrior priest GW HA SH barded warhorse

captain BSB Griffon std

35 handgunners -2x12 1x11 each with marksman & hochland

12 spearmen w/shields FC, all 3 characters here and a 6 spearman detachment

6 outriders w/ champ &hochland

2 great cannons

1 steam tank

whatcha think? I ended up winning mostly by luck & steam tank, but i know this list isnt very strong by any means and I wanna improve it

Look 3 units of gunners,outriders, 2 cannons and a stank are going to be effective regardless of what else you've got in the list.

It's a gunline - which isn't the worst thing but IMO doesn't always make for fun games - ITP armies are going to probably get through to you - panic prone armies will not.

That being said I thinkyou need a scroll caddy - priests prayers sound great but against an experienced opponent will ususally be selectivelydispelled.

Mount the characters to give you some mobility and protection

12 spearmen is fairly soft - if you are going to try and include a griffon standard block - make them bigger I'd sugges swordsmen or greatswords instead of spears.

Flanking detachments - shooty bits, swordsmen or maybe halberdiers are all good choices
