The colors and the movement of the flames are very good...
The overexposure in some parts of the flame fits perfectly... Show the strength of them... So for me you've used the exposure really well...
The crop is cool as it gives us this black space upwards and then suddenly we have flames breaking the monotony...
About the frame... it is simple and effective for my taste... Without the frame I think the crop wouldn't fit too good...

The movement of the flames really gives the idea they don't like to be shot by you and want you burnt... hehe

Great capture to me... Keep up...

ps: was I constructive???

Agreed on all the above points, and I would add that I'd like to see something (anything) in the shot that had a bit more focus/sharpness to it. Still, an interesting shot.

Good capture...Little dark though? Maybe a lighter colored framed..

Still good work!

I like the black background...
I know, for experience, how hard is to support the hot fire close to your face, so all i can say is that you have a great shot here.
For the frame i had try some orange or red for the line...

+5 (in 5) is my vote

Agree with trevorm.

Agree with Patrick who agrees with Trevor!

Neat picture, but I would add a 1-pixel orange stroke (not too bright, though) on the inside of the black frame.

Nice captureee

Interesting shot too...

nice composition ..agree with trevorn..
