Composition: Placement of the flame works well and the arm of the hard drive works as a leading line to the flame. However, the bright spots on the left are a bit of a distraction and leads the viewer out of the image.
Cropping the bright spots on the left could possibly improve the image.
Exposure: Flames are hard to get the exposure right for. In this case, most of the flame is blown out though does not detract from the image. The flame seems to provide enough light to bring out detail in the shadows. Some areas of the arm (small) appear blown out but are not a distraction.
Impact: Some impact is achieved through the use of unusual lighting (the flame).
Processing: Good choice of border. The sharpness of the main subject under the flame is good, however the drive arm appears oversharpened.
Nice idea and pretty well executed. I still like fire shots way better when there is some texture to the flame, not blown out like in this photo but anyway, nice shot.
