This is a badge commission for renguy on FurAffinity of Luna in full armor. He specifically wanted armor more in line with what a real horse would wear, so she has iron armor and chainmail with decorative tapestries over her neck and flank showing her mark.
Yo, I'm totally proud of this fyi, I drew, inked, and colored this in about an hour.
If you want a badge, pm me. :) These go for $15 and for anthro characters are waist-up.
