First Off, i think i have seen the poses some where from a drawn picture of this maybe? Im not sure if You had used it to inspire you but you have made the point og what the photo is going to be about.
I love how the cosplayers have been fanned out to space out the colours and such which really strikes the eye to love the great quality of this cosplay photo.
but besides of the photo not being zoomed in enough (i cant really see thier expressions cleary) the photo is fantastic! i cannot wait to see more!
