I confess I like the more colorful image in the tutorial better. (This is kind of Christmasy -- was that your intent?) Your wings seem too flacid to fly. (BTW the tutorial's wings are too far apart IMO.) Her hair seems to be just a bland blur. Her green body is a matter of taste but it nevertheless needs more highlighting (i.e., dodging and burning [not addressed in the tutorial so you just have to look at the 'end result' for guidance]). Add ground highlights as well. I like the wing sparkle, but the 'stars' in the tutorial (really glitter or fireflies) helped justify the width of the image.

DabLundbery, Thank for the honestly, No my Intention was not to make it Christmassy, Looking at the chop I do not see Christmas, but I do agree with changing the color of her body. Your other suggestions I will take into consideration Probably . But I do believe this was my best effort. Thanks again.

good job! best of luck!!
