You have created a cute, simple image that works well for the Challenge. You did a good job of toning down the shadows which could have been overwhelming in this image. I like how you used the yellow background, carefully bending it so there is a continuous flow of color. I would suggest that the yellow of the background and the yellow of the cheese seem to be (er) at war with each other and the result is not as pleasing as it could be. But, by all means, keep using vivid colors. They can be really exciting and unique.
And it has been my (personal) experience that toy figures do not do well in DP Challenges. While your choice of elements is up to you, this is something you might want to take into consideration for higher scores.
Finally, there is a little halo around the gouda cheese which sometimes suggests oversharpening. You don't mention sharpening in your workflow, but it is something to watch.
I wish you continued success in DPC and look forward to seeing more of your images.
