This may be based on someone else's vector, but it's what you do with it that matters, and from the looks of it, you used it effectively. The best part about this banner is easily the lighting. It actually appears as if an actual light is shining towards Twilight's left side. It also enhances the anticipation as this unicorn supposedly prepares to cast a spell during a battle. The only criticism I have is the designs in the corners. Not only are the blue and dashed corners a bit inconsistent, but I also think that they take away from the suspense of the piece. Personally, I think that the banner would be far more presentable if you only had Twilight in front of the red rectangle. Just an evil Twilight behind a dark red square and a black background would feel so intense, it would have me on the edge of my seat! You were able to use Osipush's vector to your advantage and came out with a chilling piece of artwork. All in all, I think it's nicely done. Keep up the great work, Fskindness!
