Great sculpts, love the Janissaries! Especially the one resting his matchlock over his right shoulder.
My favourite army is the Ottoman Turks of the Napoleonic wars, for which many of these would be ideal.
If it weren't for silly things like national borders and geo-politics, I can imagine you would never want for work, manufacturers would be queueing up to give you commissions.
I do have one suggestion, for when you do the guard cavalry, eg Silhitars, Sipahi Oglans, perhaps some on standing horses or lightly walking ones, not just the charging ones. Most of the time such units just stand around looking menacing until that one final charge.
(Apologies if you've done these already and I haven't seen them way back in the thread)
