I love this cosplay. I never heard of HOTD, after I saw this deviation I looked it up. Hiyosakura did a good job! The photo is placed nicely. Rei's confident look gives her a taste of badass. Great job!
It's great, except for one very tiny, but unfortunately fatal, photography flaw.
The blood splatter on the out-of-focus hands reaching for the main subject is in focus. This makes the entire shot look flat and lifeless. Try blurring out the splatter effects, so it meshes with the depth of field.
You're welcome! It was just a tiny flaw anyway... a few quick strokes with a blur tool and viola, all is well. It was a great photo underneath the splatter effects anyway. It communicates the message very clearly.
