Oh dear. I'll come to the oh dear a little later. Bear with me.
First of all, amazing artwork. The shading is dramatic and gives the impression of 'sun peeking through the clouds at dusk', the lines are smooth and clear (Cammy's left thigh bothers me a little. I think it's the blending of the Gluteal) and the detail on the nails is awesome. Two things that could be looked at a little (Sorry, but I think all artists need something pointed out.) is the placement of Cammy's right arm and the dust trail. The movement she's making doesn't click instantly, as her body seems to be twisting around the abdomen (Spinning-bird-kick like) when the action and placement seem to show her arcing her legs backward in a shin-strike. Placing both arms on big-ol' Juggernaut's thigh might make it harder to see her face (Necks would have to be made of rubber for her to look through in that circumstance) but you could rectify that by forcing the forearm of Hugo back in the impact.
The dust trail is excellent, but perhaps a little more at the start of the curve and a little less at the end would highlight the speed of the kick.
Those out of the way, this is a stunning, incredible piece of art. I congratulate you, sah.
