You considered doing any Japanese armor from the Edo Period? Not sure how easily they'd translate to Blockland's style but I think the armor itself is cool.
Ah damn, I can't read. I do like some of the earlier helmet suggestions so to add something maybe a Spanish Horseman's helmet, similar to the other ideas but with a plume on top.

are you going to make renaissance era armors and, weapons?Can you add early guns like the matchlocks and wheellocks?
