Dark Angel

You said to leave you Crit. so here it is!
The right top(our left top) part of the girl looks a little weird, try to cut closer to the hair so you don't get the lighter colored area between the hair and background. The cut and blood are a little too... what's the word... bright maybe? try to turn down the Fill %, that will make it lighter and make it stand out a little less, just mess with it until it looks right. You should maybe try to blur the VERY EDGE of the dress at the bottom so that it blends in with the background a little better and makes it look like she was actually there. The blade looks a little bug and you should use the burn tool at about Exposure 56% and just darken the blade until it matches the lighting in the room, then it will look more like it was in there too. The only other thing that I can think of is to use the Eraser at about 25% Opacity and LIGHTLY erase the tops of the lighting bolts a little bit to make it look like they were coming out of the clouds a little more, though they do look great the way that they are.

Over all though, it looks great! Especially since you are just starting with this and haven't even had Photoshop for a week yet!
