I really like your customs! I'm in the process of creating some knights similar to your customs, although I'm looking for a blue eagle knight like yours to use. (I think the heraldry on the older knights is more authentic than the newer ones.) The upcoming Saracen Special will give us white and silver billowed legs to use, so that opens up even more possibilities.
You've made great use of the Roman and Egyptian parts for your Saracens too. The men look excellent!
