Sniper

Overall the picture looks good and it seems that the pose of her gives good support to the sniper rifle, the details on the ground and the background are well made too and it does seem that you spent some time trying to get some good angles here too so that's something good, that being said, the shading of this picture might use some work like the shadow projection and, likewise, light projection too since it gives me the feel that the light comes from one point, though the shine reflected on her body gives the slight idea that the light comes from other sources, like so, the shadows (specially on her left leg) aren't properly or entirely projected, in the way that you didn't shadowed the ground like you did with her right leg.

Now this is just me being picky, but i always tend to check on the mechanism of the gun being drawn, in this case, the sniper rifle is lacking some details on it, like the bolt to get the new round on the chamber, the magazine (or clip in some cases like the m1 garand among other sniper rifles) and the hand supporting the rifle is a bit off the wooden part to support the rifle itself.

That being said, i still like a lot the pose you've chosen for this piece of art and the picture overall, so please don't take my words too harshly, if you want, i would gladly help you with some of the details i mentioned on this critique earlier and maybe learn something new together, hope you have a good day ^^
