The long golden hair, the green eyes, the inconspicuous eyebrows, the angular face (left eye and muzzle) and finally the confident smirking expression. AJ is an aura short of being super saiyan 3.
Seriously though, I really like how her fuzzy left ear reminds of a flame, which fits the warm and gradient coloring perfectly, which even more so, fits AJ's spirit and personality. Or at least in the way I like to perceive her. Something I find a little dissappointing though, is that of all the red in this picture, her cutie mark stands out the least. Don't get me wrong, the hairbands and the "thing around her neck" looks great. I just think it is a shame that her cutie mark, which is integral to her character, is outshone by her awesome accessories. But maybe that is just me. But overall I like this drawing.
Aside from that I wish you and everybody who reads this a Happy New Year.
P.s. Can anybody tell me what the "thing around her neck" is called? English is not my first language, and not knowing what it is called, has been bugging me for a while...
