I don't believe that the red and blue should be as bold as you want them to be, given they do stand out more, but they also take away from the rest of the picture.
The font needs to stand out, but it also needs to blend with the rest of the picture.
If not, what's the point of having a background?
Having the stark white, then having the flame red and bright blue, is kind of childish. Is takes away the seriousness of the picture behind it, which in this case, I REALLY, REALLY like the background picture, and I believe that toning it all down will tie the picture together, while also standing out.
the picture is well balanced, and the font is much better.
It really brings it all together.
I'm an artist, been to art college, and was in AP art all through high school...so that is my credibility.
