I've been playing too much Infinity Blade. My first reaction: "holy crap, Isa fanart?!"
My ONLY complaints are that the background kind of clashes with the character, and her hair looks a bit rushed. Just a bit. Maybe a tad. Actually, her wrist on the left of the image looks bent at an unnatural angle, and it seems like a missed opportunity to not have the polearm slanted perpendicular to the line she creates with her body. But those are nitpicks.
I love it. I love the armor, but most of all I love the depth of the image and the contrasts between the darks and the lights.
Found this pic today, it's great. Nice armor design, looks really functional and not only fantasy-like; only detail that strikes me as weird is the way she holds the sword, as I would think the sharp edge is facing inside, which wouldn't be an ideal grip for using that sword... but still that's just me.
If interested in a more complete opinion: the way she's holding the sword in this pic would work for a knife, which could be hold in front of the body to make quick, short slashes in outward movements. A sword could also be used with a reverse grip (blade facing down) but would be most likely used in a movement from the outside to the front, which would need the sharp edge facing the other side.
Well. While I would agree that this does describe the common grasp of the weapons, there's the loophole that at any time someone could adapt to a peculiar style. Or (although the author admitted that such was not the case) a scenario could be playing out wherein that particular grip precedes the as-yet unseen one-handed downward thrust to the hapless victim struggling to rise from the ground.
... I am only saying this because I simply adore this picture, and now that I've seen your comment -- *lifts hands in warding gesture* a perfectly reasonable comment, I agree -- I'll now think of that sword far too frequently when I gaze upon this lovely rogue.
