Background removed. 3 different twisted warps
step 2 of 4
Duplications and warps, dodge and burn etc
step 3 of 4
Same part warped a little and moved away from the centre, hue changes.
step 4 of 4
I took the whole thing and applied glowing edges to it, then used "soft light" at 50% opacity to bring out the detail in the layers below.
Last step :-)
