Holy flid, your art is AMAZING! A lot of people can draw, but there aren't actually that many who can just literally turn into a Polaroid camera and pop out these photo-perfect, realistic shots of people and things and places.
Of course I love your DP group pic, too; a nice blend of homage to Hartman's style while mixing seamlessly with your own. Even your earlier stuff is a true cut above the rest, in which you can see your current style and full talent range blossoming, but even while 'simpler' per se, are still vibrant and unique and beautiful.
I hope you'll only continue to draw and experiment and enjoy the medium. ^-^ I'm eager to see what you'll come up with next. I know it'll be as awesome as you are!
