The concept is silly but still great, and it's overall very well done. My only criticism is that it's easy to tell the confetti isn't real. It's too even and some of the pieces are exact copies of each other. Otherwise great work.
I can't make a proper critique cause am not a premium user... but still... i really liked the photo, just have 2 things and 1 recomendation.
thing 1: the confetti on the model's faces really bothers me thing 2: the cloning on the right is a little notorious.
recomendation: there's an out of focus piece of confetti on the hand of the blonde model, it really adds some depth to the photo, i would suggest you to blur some other pieces of confetti (or a new layer above and/or below the models) so you can add more depth.
