Never hurts to bump it up a notch, but what exactly do you see wrong with XM paint apps?
It's hard to put my finger on it. I think maybe they can work on there shading so that the colors seem more realistic. This is most evident in the faces. I think they need to change the colors they're using as the dark shading. It could also be that they need more depth and shades of color overall.... I'm not 100% sure though because I'm basing it off photos. They're sculpt concepts are so dang good that they deserve top notch paint apps.
