i feel almost bad for asking since you do this for free but since you aske for suggestions i do have some :)
the new steam tank ehllblaster has some texture bugs i think, the parchements on the shields on the side have a black edge around them that doesnt look like it needs to be there.
same for the totem with the cloth and the skull at the top of the tank, both the cloth and the crown of the skull have these black edges, dunno if this is something you could do something about.

also the demigryph rider shields seem to change in size randomly, have alot of clipping on the riders legs and just have very poor textures all around.

hochland longrifles seem to carry 2 swords which is weird.

and finally, the state troops and greatswords could do with some texture or even small model updates.

so as you can see i do love the empire haha. do with these suggestions as you wish, already thankfull for the work you done so far.
