Hi, wow another player who leads with a General of the Empire
I love the general but if your character is to be leading a knight unit it might be better tactically (and fluffily) if you were to make him a Templar Grandmaster, of course you'd have to lose the pistol.
looks like a nice list, consider shrinking the Knight units down to 6 each and make the two handgunner units detachments on your infantry for more flexibility. Also drop the level on your wizard and consider giving your non-bsb captain a pegasus (nice conversion opportunity).
I do field a standard on my small knight units and I've had good results with them, it depends how you want to use them really. I you want a major knight unit for the general to lead just switch them round so that you have a unit of 5 or 6 for flank support and a unit of 9 to make 2 ranks of 5 with the General.
