Ive been using the fire stocks she provided as well, they seem to work really well with the other stocks chosen. Not many effects are anything special going on in this sig, but you decided to keep it simple and I respect that. Signatures don't have to have c4ds or a whole lot of smudging, they can be simple and still look good. I personally really like the sig, the text could be a tad better, but overall, you did a good job.
That's not a fire stock... It's soft brushing w/ a liquify filter then some ripple and other distortions. Then I duplicated it, gaussian blurred it and set to screen. Then a bunch of different adjustments.
