Catalina quick battle pose

The pose is pretty dynamic and the placement of the shading is quite nice. I can see you're either using multiple blacks or treating them differently, to give different effects. It's good, but I think you need to push that further, perhaps by infusing a bit of colour into some of the black areas, since as it is now, a lot of the detail and form is lost because the blacks are very similar. still stylish and cool though.
