Huge fan of this series, and I loved the movie. So here we go!
Vision: My guess is that the point of view is Katniss's? The timeframe - is it during the Games? Games one or two? Anyways, the shadow and dirt are in just the right places, it really brings out the pin.
Originality: To tell the truth, I have seen shots like this before but not with the grime on the hand like that. So not that I'm saying it isn't original, just that you included some more details than others.
Technique: This shot captures the elegance of the pin, and how horrible the arena is, based on how grimy the hand looks. A great part of this picture is that the pin is actually relatively clean looking, like Katniss has been hiding it under her jacket.
Impact: Personally, I love it because like I mentioned earlier I am a huge fan of Katniss, Peeta, and the others. So this really does touch my heart (fangirl moment)... No but really, it looks like it could actually have been a part of the movie, where the screen was focused on Katniss holding the pin!
So, anyways, hope you continue with your THG shots. It looks amazing to me. Just keep in mind that sometimes the watermark gets in the way of the photo, might want to make it a little more transparent.
