Ok, I don't want to bash so please remember that.
Your figures are all looking alike. You use the round detail in all of them. Try switching up a little.
Please work on your cloth sculpting. You have the right idea but it is still flat looking and the folds are way too uniform.
As was mentioned before, please pay attention to the plastic bits. Especially since you are selling these.
Hope this gives you some ideas/help and so is constructive for you.

I like the sword, shoulders and banner. Your skill is evident, but your figures are a tad too " busy" for my tastes. The right arm is shockingly rough, and you don't seem to be very diligent about cleaning mold lines.
Less critical, but pertinent: your figures heads are always just a bit odd looking. Might just be me.
You're very, very good with putty. I just wish you showed the same attention to the plastic.
