My first picture made in Photoshop from scratch. The nebula effect is really easy to do.
I used a brown base, red mid, and purple top, along with white for highlights. Then I applied a Render=>Clouds layer in Overlay blending mode, then applied Render=>Difference clouds several times to the Clouds layer. I then duped the clouds layer and set to Linear Dodge. Then I made a new layer set to Screen blending and plastered a couple lensflares. After that I just slapped in a starfield and viola! Made in abt. 5m.
