That's hot alright. It's a little dark and would make me sweat better if a bit lighter, I think. Perhaps including a person in the shot would help, too?
Technically, this image is suffering. It seems very over-sharpened along the edges, and - despite the intense heat - you don't get the impression of heat. I think this might be a glassblower's oven - if it is, why didn't you snap the glass just as it came out? Oh well, good location, but not too good execution. (4)
