i can see that it can works even without blue in shadows, for the warm feeling ^^. It's cool that you didn't shown us what they're both looking at. That lets our imagination freely do the rest. Another new great piece !
OH I love this! There is a lot of contrast, yes, between the two characters, in the structure of their faces and their forms, but there's a lovely unity here too, you can see how they trust each other, she's got his back, he's protecting her. He's chivalrous, but she's no helpless pansy either. XD The colors are stunning as usual, I love the warmth and how it's highlighted by cooler colors...
(And I see nothing wrong with the male brawler and the female shooter. Unless the female is a ninja or built like a tank, or one of those ridiculously perfect heroines, she'd be a lousy brawler. Different gifts/strengths, different roles. XD)
One of my new favorites. It always makes my day when you post something.
