The colors are really nice, and I like that you've framed this rectangularly. I'm not sure about the focus especially on the white candies and plastic on the right hand side. Good luck.
I like your take on the challnge. Shows creative thinking. The background elements detract from your main subjects though. I also wish there was more focus on the foreground elements.
The crop here doesn't appeal to me as it looks like just a line of garbage on an otherwise unintereting back ground. Maybe if there was more colour or if the angle were different it would have had more of an impact.
