Always worth another interpretation of your work.
I prefer this to the colour version. Do you?
Generally, the way I work I keep no record of what I do to the image. This gives them a unique quality as I can never remember what I did to get here - just let it flow.
When I'm switched on however I will create a preset to use on the image again or a similar one.
In this instance, I forgot so if I need to produce this again from scratch I cant - it would be different.
In some ways I like that.
