Superb work here 8-Xenon-8 and damn that's one awesome render of AppleBloom to say the least, very good touch of realism in the way she's so common to her anatomy and style from the show, wow!
Rather impressive how well your so called testing managed to take you and even like the smaller frame and size of her design in the way it again relates to her smaller size and cuter type of nature.
Think you do quite well to achieve your skills in both the lines that you draw and even the colors you use. There's a fine level of depth and charm to your form of AppleBloom definitely wish could utilize in my own work but know well that you are an artist of great talent to take a character like her and turn her completely around like this.
While do admire the body and your pony anatomy alot think its the face for showing that dear and sweet side to her we all know best. The soft glow and charm from her eye and even the way her hair covers part of her face adding some mystery and a little bit of poh, lol.
Also great work handling your colors to making her coat appear more human like with its nice shine and getting the size and depth so to speak of her mane and tail in regards the smaller consrtcion of her body.
Anycase this is a remarkable piece done by a very gifted artist, hope you'll keep up the fine work 8-Xenon-8.
ohhh what an interesting style I'm not sure if the gradient style shading best compliments the style of blotchy line art but hey! its a good experiment non the less and it came out fantastic AB looks like shes up to something cheeky .__.
