I guess I'll go ahead and critique this. This is yet another great vector of yours. The anatomy seems to be spot-on as far as the show goes and you managed to capture that sense of surprise I think you were aiming for.
I gave originality 3 stars because the pose, while done correctly, is rather generic compared to your other more complex and interesting poses. I gave 5 stars for technique because this vector is just overall well done to put it blatantly. Nothing out of the ordinary there! The way you style Shadow Moon's hair is always incredibly detailed and it clearly stands out from the rest of the OCs out there. I would have given vision 5 stars, but personally I feel like there should be a more distinguishable color difference between the body stroke color and the shading. Oh, and the background is just stunning, but you probably already know that~
