Orgianality: Well, i am normally not a fan of alicorn OC's. But this time i like it. Not because she is pretty, but because she looks normal but still pretty like alicorn. I think that the sparkles are a lil bit sueish, but i think it is okay with her.
Technique: I can see that you try to do the vector effect with the curve tool. That is good (really good) but try to make the next time everything vector like or not, because some places isn't the vector effect used and that looks a lil bit weird.
