Well, that's about the best full ha with polearm skill I guess you can squeeze out.
You'll have two problems on foot - low damage and no athletics (though I guess the 24 agi goes a long way). So a long spiked club would be probably the best backup weapon for when you are dismounted. If you plan on using a lance, you can easily take points from ps into riding, since a lot of the damage comes from your horse speed anyway.
