Thanks Steve and Louie !!
If you have another look have just done some adjustments to my satisfaction.
It's still not cropped, will wait for the colour before i do this. So the edges are rough.
Here's a link to the completed Lum...

Will probably push the Lum further once I combine the colour.
All the best
