I really like the top one. It looks like a v3 Magic Con Deck.
Really? 'Cause there's only two versions of the Magic Con deck... The first of the three cons had no deck to go with it.
(You know I'm just having some fun with you...)
I had some time to sketch out my thoughts on the King of Spades.
Overall appearance - really gorgeous.
Those facial features - absolutely frightening! At first glance, he looks like "that creepy uncle!"
I like that you amped up the level of facial detail, but to make some realistic details while leaving others more symbolic/traditional kinda makes my brain slip a gear. I'd say make a more realistic face. The recent trend, which I like, is to go for younger courts - when you think about it, many people back in the days of royalty really were young when they held their office because they simply didn't have long life spans. But even if you want to keep the traditional, older look, that's fine - just either scale the details up or down, not in-between like this. Give him a real beard and hair, with color, something that you might actually see in a portrait. The skin can remain white, that's fine - perhaps you can "warm up" his expression some, though.
