well this is going to be an interesting critique!
Vision: of all the pics that you have make, this is by far the clearest and the most clean picture I seen!
Originality: it is almost like walking into a dream from the way you did the lighting in this one. I always enjoy dreamscapes
Technique: everything is drawn to the max I say! from the tree to applejack herself. every single detail is wonderful!
Impact: this is the most alluring of all the pictures that you have drawn. with that being said, it is THE strongest impact a picture done by you. let there be more!
I am really happy to give you this critique! have a nice day!
