It has to do with the arrangement of the animals and the composition as a whole. In Rame’s paintings all the details and the light works together to form a warm and precise depiction of the scene. I don’t see that in your painting. It lacks all the fine details, and the animals are not placed into a classical composition.
Yes, your photo wasn't very good and didn't show all of the painting, so you are welcome to upload more photos, but I am sure that my opinion will not change, and that is because of the composition.
