Instead of a ducky swimming in a ball pit he/she is swimming in M&M's! Neat idea for you also have a very colorful composition. I don't think that the lighting is flattering- there seems to be too much reflection/glare off of some of the M&M's and the beak of the rubber duck. Perhaps natural light would have eliminated that glare as opposed to indoor lighting or use of flash. Perhaps even a polorizer filter would reduce the glare/reflection. I like that you don't have the ducky centered for it makes us look at the overall composition. Lastly, crop or zoom in closer to your main subject would keep the attention more tightly focused. I think it was a good choice to have the duck 'swimming' in the M&M's but there is a little too much that he/she risks getting lost in it. Cropping off 1/3 off the top would still have the ducky swimming in M&M's but with a tighter focus on your main subject.
I like it. On the thumbnail I thought it was gumballs. It's M&M's! I think the ducky could be closer to the middle. A closer zoom on the ducky would be good too. 7
