I love how the red on the face of the man on the right blends into the background. It makes me see him as both in the background and in the forefront. It feels like an opticle illusion to my poor eyeballs. Excellent work!
Awesome effects! The light texture really adds to the piece, the gradients of shadow plus the spare use of hard lineart really makes the image have this extending-receding feeling that makes the image pop. Love the 2d+3d feel, it's quite a unique picture here!
