I think it would be a good idea to include the face graphics and busts as it could be useful. I may try to do that as its been commonly requested. More weapons would be harder to do as that's much more work. Occasionally people do commission additions such as the tower knight which is another option.
For the Tower Knights I would say I only want the Sword and Axe option. You don't have to remove the shield. I would love a World Map Character of the Tower Knight and Faces as well. No rush of course. And for the Mage Knights. You could reuse the Archer Faces as template. Ps Thanks for the first batch of faces for this series.
