Y'know. I don't like anime very much but there's a few series that have captured me over the years. Dragon ball, Tengan Toppa Gurren Lagann, Fairy Tail... y'know odd stuff. Fairy tail is an interesting one to me. It averages out to such a mediocre anime because amidst what I consider to be really awesome and emotionally moving story telling you have immeasurable tons of fan service and silliness that... doesn't mix well. Sometimes I wonder what if there was an alternate reality version of the anime that took itself much more seriously and had more feel to it? Kinda like the DBS Broly movie was a slower paced, more emotional and dramatic treat in places than the traditional DB Super anime episodes.
TL;DR: The girl depicted here is close enough to a character named Erza Scarlet to remind me of her, and the butterflies fit well with a fairy motif. I would much prefer this picture over the official Erza though, because this picture portrays a very different quality of dignity and strength that I rather like. Thanks, this picture is a true treat for the eyes and imagination.
