Very nice artwork here, very cute. The anime style is fantastic, you can try to make any eyes covered by hair semi-transparent. The overall structure is nice, and so are the perportions. The arms on Mr. Blue could be a bit longer, but that's minor. Mr. Green's mouth could also be larger, so he doesn't look like a corpse. I love the overall theme and the long tail is appropriate. You could try shading the inside of the mouth to provide depth as well. Lighting is very nice here. Fur has texture, though you could try to add more tufts but very nice overall! Love it!
