A walkthrough graciously shared by Frost Concepts on Deviant Art. I really like this piece because it shows an interesting technique that can help create unique images. You can see it applied in the second step. A very clever way of creating detail.
The effect is created by using a custom brush and applying it to the image with some spacing and variation. In this case the given edges and shapes are turned into a high tech suit of armor. What other outcomes can you think of? Where would you take it after step 2?
Hope you enjoy this piece, as usual click to get it in full size. And don't forget to say thanks!
