Sailor Sun Rebirth

My first Critic! YAY! So here goes:
I am not a professional artist, so anything I say is my opinion and its up to you how you use it, everything negative is meant constructively and not as a derogatory comment.

Firstly the overall anatomy is very well constructed and you have done very well with a pose that is definitely not the easiest.
Apart from a couple things that I will point out, everything is bending at a realistic angle and is in just about perfect proportions. (Congratulations on the torso and head especially, its an awkward angle)
Some errors that I did see:
-Her left hand looks too big, it's a lot further away from us than the right hand and therefore it should be smaller, not the same size. This is something you'll fix with practise and trial and error, references are always a great resource too.
-Her left knee seems to be facing a similar direction to the other, but then the leg continues on straight. Try and keep the knee relatively symmetrical if its facing you. It seems that you've changed your mind about its direction and not completely fixed it up. A little detail/shading on the foot would help define it better as well, but that's up to you.
-Her sword's handle isn't quite centred, and it looks to me like its pointing straight down rather than slightly towards us. I suggest looking at some swords, or anything similarly shaped, at the same angle just to get an idea the best way to go about it.
Thats about all I can see there. <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>
The shading is great, and the way her hair and skirt falls is perfect. I like the magic(?) in her hand as well <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>
She looks like a kind and good person (pretty cute too) and the sailor-moon-like costume suits her.

So all in all you've done this very well, she actually looks like she's running towards us. Your mistakes are things that you'll fix with time and practice and are nothing to worry about.
