First of all, I want to say I love this! Her expression looks so joyful just because of the apple balancing on her nose. For some reason I also like that she doesn't have her hat on. The background around her is also bright and gives a happy feeling, and the glow around her is bright, like the sun is shining on her, fitting the excellent title of 'Simple Happiness', because everything has the vibe of delight. The shading is very nice, although some of the shading at first glance looks like dirt splotches or bruises. But other than that, it's a very lovely Applejack art piece. Keep up the good work.
