Allow me to begin by saying you are absolutely adorable. Your hair and eyes and skin tone work beautifully with Aradia's colors, and you even have the correct frame, body type and bust.
Now, I gave you a vision score of 2.5 mostly because it isn't really saying much as a piece of art. Yes, you're Aradia, but that doesn't really push forward a higher meaning than simply that.
I give you a 4 because I've never seen the horns done like that before, and they're absolutely gorgeous. The only reason I'm not putting you at a 5 is because the shirt is probably not your own design, and I can't see your lower half to judge the rest of the outfit.
I give you a 5 in technique because, once again, those horns are absolutely beautiful. They're seamlessly worked into the overall costume, and I can't even see how you attached them. They seem sturdy while showing no other way of being attached other than growing right out of your head! Amazing!
Impact is at a 1 because, well...it doesn't really mean anything. At all. Sorry.
