Given your position as King of Saxony, Poland, and all-around disliker of Prussians, there are some elements of the Seven Years War that need attention.
First off, Saxon Polish Uhlans are very much needed. I'm not aware of anybody sculpting them in 25/28mm or 15/18mm:
Also, I'm not aware of a sculpt of the Graf Brühl Chevauxlegers in the short mitre cap. While it was not issued for the SYW, it was worn during the War of Austrian Succession.
For the Franco-Prussian War, I'd like more German cavalry, especially Hussars and Uhlans. While Foundry and Helion do make them, the number of poses available are not many. Moreover, German cavalry, especially the hussars, are ideal for FPW skirmish games, given their role for scouting. As such, I'd like some dismounts. Foundry does dismounted Dragoons and Hussars, but that's it. You did an impressive job with the dismounted Saxon hussars for post-1812, and there's a serious need for dismounted cavalry in this period if you want to do skirmish games. Dismounted French, especially chasseurs d'Afrique
, would also be useful for colonials in Africa.
If possible, could figures be cast headless, allowing for multiple different kinds of headgear to be sold? That might make the figures cheaper to produce, so you don't need separate casts for the Death's Head and non Death's head hussars, regular uhlans and the Bavarian chevauxlegers, Bavarian and Prussian cuirassiers, and the various kepis, busbys and czapskas worn by the French. It'd also help converting said Hussars to British ones, since the atilla is the same as the German one.
