If you have not yet completed the rendering part of this tutorial, first complete Part 1 and Part 2. If you do not have a 3d rendering program such as cinema 4d to render in, you can skip to part 3 where you are able to download the TIFF file which contains the render pre made for you.
1. Open your PSD with the render and brushing in photoshop:
2. The first thing we are going to do is add a better background than just the plain black we currently have. There are hundreds of ways to do this, but in this tutorial, we are going to use a blurred clouding effect. First select the background layer (the black layer), then select 525252 as the foreground color, and 000000 as the background color. Go to Filter > Render > Render Clouds:
3. Now apply a Motion blur of about 200 to smooth it out a bit:
4. Now add a new layer above the rest of your layers (even your color balance layer). Set the blending mode to Overlay. In this layer we will be adding "Tech" brushing to spice up the outside of the render a bit. I would recommend downloading my Tech brush Pack at GreyCobra.com before proceeding. Once you have it installed and loaded, add a few lines to the left side of the image (Use all three of the very long line tools in my brush pack, be sure to use a white brush). Also add an outerglow using the following settings:
You should get a result similar to this
5. Add some of my other tech brushes to fill in some empty gaps. Try to use each brush in a new layer for easier editing (such as applying outer glows to some layers but not others) Some layers should be under the render, while others should lie on top:
6. Time to add the finishing touches. Your render needs a name, so name it! I named mine Annexia, as you can see in the following image. Naming your abstract should be creative, try to make your name special, and add some cool effects to it!

Well, I hope this tutorial helped a ton! If you can do all of this, you are well on your way to becoming a great abstract artist! The more creative you get, and better you develop your own style of brushing techniques, the greater your art will turn out!
