I think this looks good, albeit a bit simple. I think the balance of reds and whites are good and the arm looks good, nothing about the proportions on it or the person at the bottom seem off except for maybe their mouth and eye appearing just a little bit off-center. I assume they are meant to have animal ears which is why the blood on them goes off to the sides like that. I do like that you did some slight textures for the whites and different shades for the red to keep everything from looking too flat, especially the bit of black to give the hand detail. The biggest thing thats off for me is that there is a lot of blank space. It feels like a background thats not the same solid color would be nice. I think this is still neat, so good job!
