Smudge tag + B&W = Disaster
The colored version, on the other hand, is quite awesome, the effects are fine and the flow is nice.
I find the small usage of topaz on the effects though really unneccessary.
The smudging seems quickly done, more effort would've made it detailed and it would sure put more depth which this tag somehow lacks IMO.
Maybe more vibrancy on the purple?
And just a side notice, I'm working on smudging myself. I'll reveal my project soon.
