YOWCH!
I'm sorry but I personally think that's not a very good list at all.
I've been playing OK for a while now and have some decent tournament experience (just took 5th at Baltimore
GD with them) and honestly the build I've had by far the most success with is based on 3 Butchers and a Tyrant.
Also I use a Multiple Small Units list (units of 3), where the only command option I take is a Bellower. Standards aren't worth it (and give up
VP's) and the Champs are overpriced.
With units of that size, you won't get all that many attacks in, and you've really only got 4 units that can really charge in and do a whole lot, which can easily be re-directed or shot down to an insignificant number.
I would seriously consider dropping all command options except the Bellowers, and then taking those units of 6 Ogres and dropping them into two units of 3 each with a bellower.
The more units you have the more you can threaten and the more you can bait/flee.
Also your Tyrant is way expensive. Most expensive I go with him is 306 Points, screw the sword gnoblars and I've found that I don't miss not taking Heavy Armor either. I generally run Longstrider on him, and it's paid for itself so many games it's not even funny. The Tenderizer/Wyrdstone is great, though the luck gnoblar isn't necessary.
the Bruiser is too expensive for what you get and honestly 3 Butchers is what will win you games with Ogres. Literally the more I play the more you see what a difference the magic makes in you actually winning the game. The Stubborn Spell, and partly the Regen spell alone are what will keep things pinned down till you can flank it, or while you setup other important things, especially against ranked units.
If you were interested here is what I run for my 2250 List, it will give you an idea of what works for me after experimenting with different character options (mostly Tyrant, Bruiser, 2 Butchers, or just Tyrant, 2 Butchers) until I settled on taking 3 Butchers for the army:
