Wow, what an awesome bonfire! The purple is really cool, but the blown out white sections all over are WOAH, really bright! The solid black bacground and lack of noise are great, but the whole thing looks pixelated. I like you cropping, but perhaps less black on the bottom? Score: 4
The purple glowing wood just looks unnatural... its just weird on such a shot IMO. i guess this was done with a hue adjustment to get the flame orange. Also, the picture looks too pixelated (jagged) maybe because of digital zoom. But the focus is just right btw. I hope this comment was useful. Good luck! :)
