To any fan of My Little Pony, it is obvious what character is depicted here while you still combine traits not usually seen in the usual humanized Twilight Sparkle, such as the plaited hair, and the body colour not being shown obviously in the clothes.
Whether it was your intention or not, looking at the position of Twilight's raised hand, it resembles a horn without making the drawing too anthro.
It is clear that a lot of effort was put into this, and however boring it may have been is wll worth it.
The style is very sweet and provides more lighting and shading than I usually see in styles like it.
While I lack the proper artistic vocabulary to do a description justice, I will say that it's exceptionally pretty. It just has a great look with really brilliant colors. There's a casual girl next door sexuality to it while still holding on to that magical quality attributed to the character. Outstanding work.
