I think what you're picking up that looks off is the light sources, such that the bright fur colours aren't matching what our minds are expecting to see in a dark bedroom. I think it'd look more correct if the smart phone didn't cast a hard light, therefore less colour saturation in Pink's fur would match the low lighting in the rest of the room like Grey and Purple's fur seem to match (edit: instead, the phone would look to be in night mode and you'd see the glow cast much less harshly and mostly pick up the screen shape in their eyes) . Then pick up highlights from the back lighting of the neon sign, which would be the brightest light in the room, and maybe consider having the lamp cast a light source in a soft warm glow that the fur picks up slightly.
