Rikku- warrior

She's very interesting and pretty. <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)" />
I've never done characters myself, so I won't say anything on the design, other than it's pretty cool.
However, I'll comment on the composition of the final deviation, and any anatomy aspects that feel awkward to me.

First of all, the current full view has too high of a resolution for this work - the lines become blurry - it would be better to choose a smaller size, to give sharpness to the details.

Second, the half full rectangle/frame behind the figure - feels like a line you've forgotten to erase. If it is, in fact, addition to the drawing, I suggest making it bolder; also, if possibly, I feel the composition would work better if the top line of that border is brought lower - say, slightly above the level of her hairband.

Third: I've seen drawing styles that thin down the knees to almost nothing, so perhaps that's what you're using here... However, they, especially the right one (left one for the viewer) are so tapered down from the thigh - it is too disproportional, and jumps out at the viewer too much. Perhaps there's a way to keep them just as delicate without moving so much from human proportions.

Forth: the right arm - from elbow to wrist - is too short. Feels like the elbow is too low - perhaps a mistake mainly due to the clothing choice.

Firth: the left arm: so I tried that position.... The way you drew her, it feels like she's pushing her left shoulder forward, in which case her elbow is too visible.
(And honestly, I think in either case so much of her arm, and then her fingers, would not be visible... Or if you give her such elongated arms, both should be of equal length.)

Final: The beginning of her boots - again, thicken the lines - it looks good, gives her stability in the white space - but needs to be more confident to make the necessary effect).

Keep it up!
