Love how bright and expressive the colours are!

Vivid colors! I like it. It's eyecatching and striking, and her pose looks solid and dynamic, if curved a little. The composition is good, although I'd suggest studying how people stand in ready stances - it looks like she's curving over to her left (our right) a little. It might just be a perspective thing.

I'm going to go history geek on you now, so don't take anything I have to say as too personal. Just my analysis as an armchair arms and armor buff. :0

Her armor is interesting. It looks angular, which suggests almost futuristic manufacturing - most historical cuirasses and breastplates tend to be more rounded, as that's the natural shape something assumes when you curve it by repeated, gentle strikes with a hammer. It almost looks like Imperial Guard flak armor. I have to wonder what the story is about that. The arms and pauldrons are done excellently and look like they offer a lot of protection while keeping her arms mobile. Generally people would wear soft armor like chainmail, sewn into the undergarment, to protect those areas as they're vulnerable to a thrust in close combat, especially the armpit and the inside of the elbows. She doesn't seem to be doing that, but then again I don't know the story behind the picture. http://static.fastcommerce.com/cont.....0px%5B1%5D.jpg

Scale armor for the stomach is unusual, and a nice touch that renders it fantasy-ish while still being practical. :)

The sword I can't wrap my head around. The blade itself is very short, almost nagamaki-like, with fully a third of the thing being handle, and a good bit of that being ricasso. It also has no crossguard, just a hand protector on the ricasso. This is... unusual, to say the least, but isn't a completely impractical proposition. I suppose her hand position would give her good leverage. This is the kind of sword that uses its handle's mass, rather than its pommel, to counterbalance the blade, which is unusual (again, the nagamaki is the only one I can think of). I can tell you were likely trying to diversify it, make it look "out of this world" while still being practical. I don't know what I think of how far you went there - I hesitate to call it invalid or impractical, just odd. Why does the character use a weapon of that type? Good question to ask.

The blade's shape itself is very odd, too - I don't know of many swords that start out thick, taper thin, and then get thick again. Generally you don't want the point to get thicker as the thinner your point is the better a point it is, and with the blade behind it narrower than the tip is, it won't make the tip any tougher either. I could be wrong about this, of course. Not every sword has to be a standard cruciform one, after all, especially not in fantasy.

Anyhow, it's an eyecatching, well-composed picture, and that's what matters. I don't mean to talk your ear off with critique, so I'l leave you with that. :)

Thanks a lot, don't really have much to say (also I just woke up :) *________*

The pose - I used references to make a rough 3D model pose, then rotated it to get the perspective I need.
Sword is based off real designs (can't find the ref now, my internet connection is a bit broken), just a bit exaggerated.
