Brutal? Nah, just some critiques--not criticism ^^
*crack knuckles*
Probably the problems are the proportions. You should be careful not to make it seem like her legs are too short and the torso too long.
All the way to the bottom of her breasts it seems fine (just a bit more fine tuning with pratice)--now here try to lengthen her upper arm and keep in mind that the elbow ends approx. where her waist is.
Now, her waist shouldn't be that long, shorten it just a tad bit to keep it in proportion with her head (heads are usually the basis for the body's proportion. Like in a real human, the body is usually 6-7 heads tall).
Her hips are slightly not wide enough. And keep in mind that what really make the curves in the female body is where the thighs are connected to the hips. I think Sadamoto (illustrator for Evangelion) exagerates this--go check it out to get an idea about it ^^
The length of the thighs are actually great! It's only because of the torso looking a bit too long and the hip too short that make it seem to be not in proportion.... all you need is practice practice pratice ^^
Now... some tips on the color.
Preparing the line art is essential. I would probably clean it up a bit by erasing the scratches and what not. You also should go to:
Image > Adjustments > Brightness&Contrast...
(or Levels, or Curves, they basically do the same thing but B&C is a bit easier to learn)
And experiment it till you get a nice crisp line art. Sometimes you gotta have a good scanned line art in advance--photoshop can only do so much with a badly scanned piece.
I won't go into about the colors themselves but I will say a good way to "protect" your line art is to use the Multiply layer. It will create a transparent layer where you can color without damaging your original line art and also have the line art still come through.
I think I have a screenshot from a screen tone tutorial of mine :

Now, practice practice practice! It's acctually very nice considering you're new at anime style art ^^
