Love your work as usual, but I do agree with the comments about the tan line. I'd get rid of the tan line altogether, especially if you envision him wearing this particular costume on a regular basis. The second suggestion I would make is to make the cape pop a little more. The color comes off just a touch too drab. But again, I really love your renders and look forward to seeing many more! I'd love to see you take on Joseph Gordon-Levitt.
Yes, I mean make it less apparent. The tan line looks odd since you'd think he'd be wearing the loincloth and tanning where a swimsuit or pair of shorts would cover. It's a small detail, I know, but one I noticed.
