Composition: 8, A quirky composition, but it works for me.
Technical: 8, A little bit of noise in the darker areas.
Appeal: 6, It's funny, but there's not much of an appeal factor other than that, for me.
Challenge: 5, This would definitely fit a *blue* challenge better, as that color seems to be the impact. The yellow duck, for me, is just an after-thought.
Overall Calculated Average Score: 7, It's a nice photograph, but needed to be stronger on the challenge in my opinion.
Haha, chillin' in dish of...gatorade? jello? funky blue liquid?
I think your choice of colors here works well. My only concern is that your duck appears to be reflecting too much of the blue juice. Perhaps if you illuminated this side of the duck with a directed diffuse light, he would be better exposed...just a thought. Bumping this one up to a 6.
