Something I want to point out it that not only is shape and composition important, but your art also has an additional feature that makes it stand out and different (well, from my own style at the very least). I love how your pandas are textured. It even looks like paper craft of some sort. I assume these are digital pieces, but different "paper textures" and subdued colors create such photorealism, it's amazing.
