I moved this to the REQUEST A TUTORIAL forum. theres more than just the tutorial forums
anyway, i'll see what i can do and if i can duplicate this effect
Edit: this mainly done with smudge & blur.
Make a selection of the object you want the glow behind (cntrl + click the layer)
Fill it with the color you want your glow
Then use the smudge tool to get teh effect you want. It'll take alot of patience but it will probabaly look better in the end knowing you did it
