Although the image is scaled down so I cannot evaluate the pixels, I can see from the image some glaring errors. The purple background mixed with the red strains the eyes. The shadow for O2 doesn't look round enough, and makes it look flat. The flipped animation in the center also flips the shadow. The red background just looks like random scribbles with the pencil tool.
I'd recommend following some pixel art tutorials, as well as general digital art tutorials. They will teach you better art techniques for shading, use of color and line form, which are all lacking in this spritesheet. I wish you luck!
