That bling effect is nice and subtle, I like it
Here's another (for v0.98.9):
It uses Additive on the particles and Overlay on the layer, which gives it those weird, smoky edges.
Note that this one won't look the same in 0.99 because it uses the old Overlay, which has been changed. (So don't toss out your old Overlay shader when you do the final switch to .99... save it and rename it something else. Even though it's not a proper, true-to-life Overlay, it can still do some cool stuff.)
