Layers - Gold Mining left overs.

The 80 metre high side of a slimes dam . Residue from the gold

Very good idea! I would spend some more time in photo editing software to enhance contrast (local contrast using unsharp mask) and saturation. You should make the surfaces stronger with darker shadows.

In this photo I place more value in presenting an accurate image of a visual phenomenon that is unique to my province, Gauteng South Africa. PS'ing it would change that.. thank you for your opinion, it is highly appreciated.
