Normally, I let my terrific assistant take care of all of my shading duties, but I had this vision of how I wanted this time/space portal thingy to look, so I took it on myself. Big mistake. It took me a good three hours of playing and tweaking and squinting and starting over to get it right. My assistant probably could\u2019ve knocked it out in 10 minutes with better results. Still, the sci-fi nerd in me is pretty happy with the results.
