the cosplayer needs to lower his head more. It's not Levi-like for him to have his head tilted up like he's arrogant. instead, his head is tilted downwards slightly, as if in deep thought.
the shot could be more interesting if you moved Levi to the left a little (talking rule of thirds here)
Law did tried hard to not sneeze in our faces but well, I think it is our bad too since we were above a cliff and that I didn't want to cross the barrier to have a better angle shot ; )
although is you were trying to 'open your eyes while bathing in the sunlight, a side view shot plus a bit more back ground would be better. or maybe Law trying to cover his eyes while looking up?
and the picture you linked me was taken at a low angle, hence, levi looked as if he has his face tilted upwards, but not really. its just the angle. but this picture is like, taken at a normal person's eye view, hence it looked slighty off...
it is simply amazing that you went all the way up a cliff to have a photoshoot. (i want one too! the photoshoot lol) but it rly is awesome. nince job~
