Well the colour is spot on for what i wanted, coincidentally i actually had already arrived at the lighter colour, but that dark colour/s are really good.

I just figured i would give the who thing ago, see what i can pick up from it. Im only having trouble because i am new at this and still finding out which bits do what etc. I am sure ill get there in the end, i am just having a play around with other mountain techniques at the moment with the suggested colours. Its blending them into the main desert colour that is the current challenge, but ill see how they are with these new colours.

Thanks again and thanks for the link
