I like this a lot, I think works like these (This and Sniper Wolf) work with your style, and I prefer it to the array of cartoon girls done up in your style (that's just personal tastes), I love the curves, the detail you put into the shading and the gun, her hair is bouncy and vibrant, and is still in the style of the character while looking more realistic (as realistic as game girls can).
She has nice curves, well proportioned and has a really well built anatomy. You did really well with this, I look forward to possibly seeing more like this in the future! Great Job.
