I began by looking at a flame cycle in order to figure out how a flame can be animated.
This is my line drawing flame test. I was pleased with the results, it took a few attempts but it looks good, I then imported the image as png sequence into photoshop, and re-created the flame in colour and neat.
This is the final version of the flame, however the version i actually used was a png sequence and not a video.
I then looped the sequence and placed it on top of the wooden sticks beside the bridge.
