Well Appollo3 is wrong about the
BSB, he can take a magic banner and a virtue..
Explicitly allowed in the Bretonnia Armybook
On Errantry knights and magic banners he is right, and also on the 1 skirmisher unit per army.
As for the army itself:
Green knight special character, banned in most tournaments and quite a few friendly player don't like to play against
SC.. maybe he is cool butmake sure you have a replacement
General well Ok I guess
BSB banner of the lady: to expensive for what it does.. forget it excist...
Damsels well they should be both on horses, joining a knightly unit and sharing the Magic resistance with same.. Unit protects Damsel in return against Magehunting..
The link hereunder gives many reasons why a damsel needs a horse, read it

I would change 2 dispell scrolls for powerstones if you have them both
lvl 2
KOTR unit joined by 2 General and
BSB, atalk about all eggs in one basket!
KE well one unit needs to drop a magic banner as said before but otherwise ok
Bowmen, join the units and make one big unit form them 20 -25.
But drop the light armour on them a 6+ save isn't worth much anyway, and S4 attacks will ignore it totally..
PK Ok unit

Trebuchet OK
Against Dwarfs you don't need dispell scrolls at all and with the dispell dice a dwarf normally has forget damsel and trade their points for more troops
4 dispell scrolls are over the top, unless you go up against a very magic heavy army..
But even then 3 scrolls and the chalice of malfleur is a better setup
You also have only one musician, try to include them, they don't only help with rallying but can be the difference between winning/drawn combat or draw/lost combat..
