That fire should have a slight glow to it, make it brighter and hue shift more. A good palette to go for is dark purples to bright yellows, and everything in between is your standard fire hue shift, red-orange. Also, make the base more complex, like something Neo-Classical out of Infinity Blade. Brighten up the colors too, and avoid specular highlights that are one pixel unless there's very little contrast with the surrounding areas (your sunglasses).
