This is a full bodyart on Female titan from Shingeki no Kyojin (Attack on Titan) by Lleye, one of the most impressive Female Titan Cosplay I've ever seen, and the only one that I think is most similar to the one in the anime, I'm sure it takes a lot of effort to paint Lleye's entire body and make her look like this (its body painting right?).
Environment in this Female Titan Cosplay photo looks very lively and dramatic, dust effect reminded me of Racoon Corps outside walls expedition in the anime (caused by many Horse riding), aside from her body posture I think everything looks perfect here.
