I particularly like the detail on the red "x" in the center of the white square.

PROtip: Devianart doesn't allow for remote image leeching. If you can see the images, it's because you already have them cached on your browser but we do not.

As for the images themselves, I'll leave that up to the people more proficient than myself, but I think you've got quite a lot to learn about anatomy, characterization, and shading.
