It is generally recommended by most medical professionals that you stop scratching at the surface. But I know what you mean by that itching thing. I got one terrible itch right between my shoulder blades as I type this. Not being a contortionist I will be finding relief on the nearest door jamb.
And what do you mean 'do something a bit different'. Have you actually done more than one of the same thing?
A great job with this image, Bruce. I like the textures in the background.
You done a neat creation here pal...
