I think that is a pretty solid list. You have a fair bit of magic (5 power dice?) so you may get a few spells off, and your magic defence is sufficient for 1000pts. Also, I like the fact that you have 2 units of Crossbow dudes to take out light units or fast cavalry, the spearmen to hold while the Cold Ones with the noble flank charge or take out other things, and finally you have your RBT shooting at whatever looks tough!
I like it, good job. You do however have no Dark Riders
although I don't think they are really needed in this list....so anyway...yeah, good list!
