Okay, so my plan is to spend three days on research (done; Drogo, Hound, Daenerys, Baelish), four days on thumbs/concept art, and six days on studies/Final (which would leave two days for tweaking/feedback). I've been exploring a few ideas mainly with Khal Drogo. I Also did some concept of Drogo as an egyption but realized that Egyptians didn't actually have hair.. damn :/ It's hard to find a culture/era that fits with the character but I'll keep looking
It's great you put so much into concept exploration!
As for egiptians - I believe they kept their hair, only priest shaved their heads IIRC. It's not visible on faraons since they wore those special crowns/hats.
Like the others said, awesome idea! I think Daenaris is too hidden in that comp though, that's a hella sexy dude he could benefit from showing his lady off a bit more : )
I kinda imagine them like outlaws or something, Bonny and Clyde type thing, maybe a bag with a few bloody / burnt bills poking out of it and some guns / gunpowder marks on their hands!
Lovely comps. As for the one you've chosen (and I think it's the best one), I'd either expand the canvas just a little up or move the characters down just a bit down so his head was closer to the sweet spot (rule of thirds). Keep this up, you're doing great!
Edit: and it's good you're going outside of your comfort zone and study motocycles :)
