Polish Artillery 17th C,
No problems here.
Polish Winged Hussar 17th C
But a word or two about this.
Winged Hussars or husarze as they are called in Polish (Husaria is the name of the unit) are quite a legend in Poland. In history, in culture, as an icon, in pop culture and still present in military badges etc.
That means there is an awful lot of sources, some of them confusing.
I will try to make that simple.
Husaria was reformed three times in the XVIIth century. The main reform which also happend to councide with a change in fashion happened in the mid-XVIIth century.
Husaria c. 1647 can be called the best looking and the best trained husaria ever. Unfortunatelly most of those veterans (mostly cadres, officers and most professional soldiers) were lost in ambushed while fighting on foot during the Cossack Rebellion, especially at Korsuń (1648) and Batoh (1652).
Anyway they were quite similar to what you've made, but there were some differences.

Namely the armour and the pennant which usually was white and red.
Also they were often fighting using a longsword called koncerz which as before (earlier husaria also used it) was taken when the lance was broken which was supposed to happen during the first charge (lances were one-use only) just like here:

roughly as shown here (the formation is wrong - they were charging in a close order, but that is just a movie anyway).

Overall - change the pennant and make some minor adjustments to the armour. The hussar should also rather discard the lance after breaking it than keep it.
Polish Pikeman 17th C,
Looks good.
Polish Musketeer 17th C,
Perhaps the furcap could be modified a bit?
see this (BTW - there is also early grenadier shown here):

I think it could be smaller or the fur made a bit more brownish.
Polish Pancerni,
Probably the only animations made in this pack which I didn't like at all.
I think the Iron-mailed should be in more metallish shades. The cap isn't the best part too.

(ignore the lance - Lithuanian Petyhorzec is shown, but I will explain below why it is almost identical).
Also those guys very often were using carbines. They even fought in a caracole when necessary (sometimes called wężyk - little snake).
The bow shooting animation might be used to produce light cavalry.
(explained below in another post)
Polish Hussar 18th C,
They appeared, true, but if you want to you could make XVIIIth century Winged Hussars and add it as well.
The main difference would be winged helmet. I can provide images if necessary.
