Some thoughts on future edits I had while looking into all the new stuff (which is all really impressive, good job!):
To add more kinds of variants of generals, I was thinking things like some that have no helmets and just a neckwrap, or some with more barbarian looking cloaks/trinkets to make them look like that's where they've been campaigning. Just little details. Another little thing I thought of was the use of the roman armguards that I suppose are unknown to some. If you check under Caesars battlemap entry in PFM you'll see what I'm talking about. I made a basic kind of general using those and some other bits and bobs and it came out like this:
I know you cant see it too well, I was just trying to do something cool or whatever at the time, but its basically what you see, with the hellenic officer cuirass underneath. I think it looks kind of nice and the cape gives me a sort of General Maximus vibe.
I was also thinking about changing all the generals, mounted and otherwise, to use swords with or without shields. Was thinking without, but its whatever really. I gave it a try and couldn't work it out. Perhaps it's something you'll find interesting to attempt. Or maybe not. In any case, hope that gave you some inspiration for future work. You're defo doing some sick stuff on your own though so big-ups.
