What I really like about this is how the red on the model's lips matches the outfit because I have never had the chance to see the true color of Rei Hino's lips before. The outfit is stunning and the fire textures match Rei's element. Whoever watched Sailor Moon knows that Rei also has a golden tiara on her forehead; it's really hard to tell if there is one here too so I'd suggest showing it a little bit more next time (: Perhaps using some higher heels would help too! You should also try changing the background. You don't want to burn down those trees, now, do you!
Overall, this is an excellent cosplay of Rei Hino! Hope to see more!
