Oof this angle, I should probably attempt it again but I still hate it from my last attempt x_x

Now if I'd caught you during the sketch phase I would have suggested centralising the gun a little more and turning her shoulders (and possibly entire body) to line with it (I'm currently assuming from the angle that the viewer is getting shot at least towards if not at XD). From this particular angle her head probably needed to be straighter (I have a feeling from the previous pieces that you really like drawing 3/4 heads XD) as in looking more forwards towards the viewer and possibly tilted sideways to sight down the gun if you wanted something a little more dramatic.

That face rendering is looking really great so far, and I love the swooshy hair shape, that's going to look amazing when you're done, and everything else is coming along nicely :D
