u kinda messed up because it doesnt lok real
this is because the lighting is different for both images and by lighting, i also mean the hue of the lighting...
the anime image has a bright white tone to it, while the sandy background has a yellowish hue to is
to fix it, just put a warming photo filter for the anime image, and make sure u put it on clipping mask so that the photofilter only effects the anime and not the background as well
