H mate honestly, theres no Topaz in this attempt, i purposely kept away from the tool just to see how close i could get with any of the standard tools in CS5.
Its a combination of layers with varying colour blends and smudges, i used three layers worth of DIFFUSE and then altering the levels within each effects layer via transparency controls and lighting, i also did further paint overs via paint brush and again more smudge, a little burn and a final diffused layer gave me this.
I also used the paint brush very loosely and made the brush size purposely larger than i actually needed to give a thrown on effect, i want it to look loosed and relaxed.
Topaz is a really nice addition but i have only used it on the one puppy image so far.
Edited to add, and i can't believe i forgot to mention it, LIQUIFY...
