There's a metric ton of great stuff in here. I'll never be able to cover all of it but there are some things that stick.
Your Portuguese cigar smoking, monacle wearing, moustache growing, giant sword swinging mass of power is easily a standout. You don't even need to see his armour everything you need to know about this guy is in his face.
Your Scottish shortbread tin mascot gets my approval just for not being ginger (a stereotype which can die without anybody losing any sleep over, by the way). Very simple and smart use of the tartan pattern to switch the Greek robe into a more appropriate tartan wrap. He looks like he stepped out of history book. One thing I would maybe lose is the tattoo on his right arm, unless I've missed something it seems a little out of place. Scotland approves.
I'm not really into putting blood splatters on my characters but with Curse it's combination of the look and Tira's style which make him quite unsettling. You should definitely send this to the Ukrainian Toursit Board, though.
King of Tanzania is absolutely superb. Nice use of colour and not cluttering him with too much unnecessary rubbish makes him ooze power and presence.
Man, this is just page 1. There's LOADS. The Irish guy, the Crusader, the Assassin, the gypsy, the Spanish dude, the Spanish dude's mother-oh wait no, sorry, not her. The knight, the Mongolian, the Atlantean...there's just...so...many.....and they're all GOOD. Clear sense of identity and well put together.
This gallery is superb.
