Coppernight Hold

If you would like to add some depth to your rocks so they don't look so much like flat slabs of stone you can use the Dodge/Burn tool. Just burn around the edges and a little toward the center of rock, then use the Dodge to lighten the center and blend things in so they look right.

Here is an example of what I'm talking about. It requires a bit of painting but it's just a rock so it's not like it has to be perfect. In the example, I used your image and just burned/dodged around the rock. Things are darker towards the edges and lighter towards the middle. Maybe I shouldn't have used such a round rock but I think you get the idea. It seems almost like the shadow is too circular to me but that's for another conversation.

Hope it helps, keep up the good work.
