This shot is quite interesting... the red tone seems to accent the fire theme quite well... I like the 'abstract' nature of the shot, but I'm not really used to seeing much 'abstract' in postcard themes. I also think the photo would have more impact if it was a little bit larger. The addition of some 'Hawaii' text on the image would also probalby enhance the postcard theme quite a bit as well...
nice to see something that isn't a landscape, very exciting subject. The lines of the stage in the back are distracting - would like to see the fire eaters face
The resolution seems like it could have been higher (might just be a higher ISO Causing a grainy feeling in low light). I like the concept of this picture though.
