Here's a quick look at the processing done to Malfunction.
1) The Original
The image was shot with a cool white balance. I normally shoot with a custom neutral white balance, but for this image I thought starting off cool might be the best choice.
2) Color Temperature Tweak
I found the resulting photo a bit too cool, so I adjusted the color temperature to be more neutral (but not too warm).
Photo was given a clean-up. This was primarily a dust edit on Vader, but I also removed the slight edge you see in the top left of the original photo.
4) Color Treatment
Color treatment applied, giving warmth to the highlights and cool tones to the shadows. A slight vignette helps set focus. Popsicle also changed to red.
Lightsaber effect is applied to the popsicle.
Vader is given a warm glow to help sell the idea that the lightsaber/popsicle is actually illuminated.
And that's it... !
