The thumbnail actually looks like it is from the game; that's pretty impressive! Well done to both you and the cosplayer, you captured the action of the cosplayer in such a way that I get a sense of nostalgia when viewing this piece.
Your choice of landscape was spot on; I have no idea if you may have used some kind of lens filter or if this was 100% natural (I'm no photographer, please forgive me if I'm inacurately describing the camera) but the blueish leaves and the sooty looking path really match what I recall from the game. It was either very good luck or very good planning such scenery was avalible! The scenery is what makes this piece stand out from the other for me.
The only imperfection (if you can even call it that, it sounds a bit harsh) I can see are the blurry light spots in the bottom right corner and up the side. I don't know what they are, but that are a little distracting. Other than that, this is a good cosplay photograph, nice capture.
