I've been looking at resources for lighting and some of them had this approach. I'm a fan of the scattered glowing speck effect that's shown here, and the larger light sources add some interesting elements to the piece.
One thing, though, is if there's light coming from the orb on the right, it'd likely be lighting up the right side of the guy along the sleeve, if not just a little. That being said, is the main source of light coming from these orbs? Or is it supposed to be coming from behind him as it's showing? Cause it'd be interesting if it was only those sources being applied and the back of the cape was dimmed out to only show lighting along his left shoulder if that left orb is in front of him.
Another thing is the effect the lighting has on the hue seems a tad strong. Given that there's a slightly blue overlay throughout the dark areas, the red that it gives off seems overpowering.
But I absolutely love how there was no need for blending smudges in order to make it look good. Definitely my favorite of the ones you've made recently.
