Thanks again everyone.
Maybe the challenge i was going to put forward after thinking about it has been done before or would be too boring for a challenge .
I was going to say or put forward that the challenge was to only use The Built in tools of Photoshop, The Brushes and mainly the tool i used on this image which was the WARP tool.
I used 1 image of a rock and duplicated it many times , then merge them together and warp them to create the shape rocks in the image. one image of the funny shape rock in the middle and the rest was painted, lighting,atmosphere, and lights etc.
I also used one layer using the clouds filter, then used a mask, applied the same cloud filter to the mask and then inverted the mask. Then used the perspective tool which all aloud me to get the main clouds and atmosphere and then used soft light, then painted over that.
So the challenge i was going to do was to use 2 main images and warp them in to any image you want them to be, only using the tools of Photoshop paint or do or add anything you want to create the overall image, but i guess that's a boring challenge .
But thanks again everyone.
