Okay this is my second critique, please bare with me I am going to be as honest as possible! Sorry to sound harsh but I hope this constructive feedback helps you! I am not a professional artists of anything.... but I would sure like to help you improve your artwork ^__^~~~~

Good quality about this picture
First off it's not bad start for drawing a female considering the fact your gallery contains quite a lot of animal artwork. I like the colors you have used for the background the shade of black and blue have unity together making them fit perfectly together. I especially like the huge white line in the background makes it feel like she is focal point of this image.
Overall, it's a pretty good picture for a person who doesn't draw female or male figures <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)"/>
The way you draw the head is also pretty good, you seem to know how the way the hair flows aswell. Just need to learn how to draw hair properly few more practices and you would be good in no time <img src="e.deviantart.net/emoticons/w/w…" width="15" height="15" alt="" title=" (Wink)"/>~

Negative Quality about this picture
Okay, your female character lacks anatomy structure you really need to focus on the curves of the female. From what I am seeing at the moment she looks like a stick, she has no breast and no shaping on her hips and legs. Normally female figures have an hourglass figure, having a balanced curved shape to give composition for the breast and hip to also define the shape of where the stomach is. Her arms are way too long, they normally should have shape between the wrist and upper area of the arm (should show where the shoulders are). You also need to focus on the structure of hands, seeing from the image the fingers are unbalance and out of portion. (Don't worry the hands are the most difficult part of the human body, trust me I even have trouble drawing hands myself LOL).

You need to work on your shading, the shading appears to be quite exaggerated making them look very unrealistic. I suggest you learn how to find your light source, learn how shadowing occurs when the sunlight is directed in different ways. This should help you more with the shading making them look more realistic. Also work on your lineart, if your lineart is perfect! It will help you color your artwork much better. Lineart is the key, because it helps define the light source for shading from the line weight you need to show thickness and thinness on your lines to give your characters a bit of dynamics, and to also give a little bit of shape.

Right now just focus on how the human anatomy is structured, and how shading occurs~

Please don't take any offense to this, this was my opinion on what things you should improve <img src="e.deviantart.net/emoticons/a/a…" width="19" height="19" alt="" title="Sweating a little..."/> I am sorry if I offend you but I hope this constructive feedback helps you in anyway <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)"/> Good luck!
