Those are faction symbols. Like how you would wear your faction symbol on banners, flags, etc... Its only mockup very basic armor right now till i get styles figured out.
This is still work in progress but something i been working on.
I plan on making many different armor and weapon types. Im slowly building an RPG system. What you equip will actually show in battle and in the world when you can see your characters. im also going to most likely have a first person and 3rd person mode for when your in the world.
Looking at it from the perspective of someone who doesnt know anything about how games are made i still see tons of work that is needed. For an example... Why are there windows down by the water? It doesnt really make sense to have windows there. The bridge also doesnt make much sense. The bridge would make sense if it was a drawbridge with somewhere to pull it up. Id put a permanent stone bridge there with sides. Other than that not to bad. sorry if I sound rude. Im not trying to sound rude. One way to good game creation is to look at all your stuff from the view of the customer(even if you dont sell it for $ your still selling it for reputation).
Hopefully these tips were useful. Keep up the game dev learning(im still learning after 11 years).
