First, you can give point totals for a unit/character, but please don't give itemized price lists like you have. That can get Dakka in trouble with
GW's lawyers. Please edit that as fast as you can!
Second... Nice start of core troops, but you might want to consider changing one of those spearmen units to something else for some flexibility. Perhaps a unit of 5 Cold One Knights without upgrades (the upgrades really don't add much to COK for the steep price), which comes out to the same price as your spearman units do. Or perhaps a unit of 10 Witches with Standard and the Banner of Murder (same price again). Or 10 Corsairs with Standard and Sea Serpent Standard (once again, same price)...
You know, that's wierd! Three perfectly viable alternate units for exactly the same price as your spearmen...
Or you might consider a smaller replacement unit (say, 5 Shades with Great weapons) and using the points saved to give the spearmen the War Banner. +1 SCR is very handy for a unit that makes it's living on SCR!
The sorceress looks fine, that is one of my standard builds. She is useful both for offense and defense, and with her own Power of Darkness spell she should give the other side more magic than they can handle.
