To give more power to the laser beam I used a picture of an explosion I found on the web (Fig.11). I selected the fire area with the Lasso tool and dragged it on to my painting, then converted it on a Screen mode level (Fig.12).
I duplicated and scaled the layer to move it on to the building in order to add more fire and sense of destruction (Fig.13).
Time to light the fire! I created a new layer that I filled in black using the Paint Bucket tool and then converted it to a Color Dodge mode (Fig.14). Our black layer becomes transparent; at this point I used a brush and a warm yellow and orange color to paint over the lights in order to make them incandescent and bright.
I added also trails of missiles in the sky to give the suggestion of an anti-aircraft presence (Fig.15).
Arriving at the final steps I wanted to spend more time on the explosion caused by the laser, in order to add as much realism as I could by painting debris and sparks of fire using my brushes. I also added haze and smoke especially behind the giant mech to separate it more from the background (Fig.16).
I love to play with light, so using the Color Dodge layer again I spent more time illuminating my mech with other touches of orange and yellow to the armor, especially the parts most exposed to the explosion light (Fig.17). I added a touch of blue to end this phase and jumped to the final tuning.
I added final touches to set the ultimate colors of the scene. I gave the painting a warmer tone and a bit of contrast using a Curves Adjustment Layer andâ€¦voilÃ â€¦The Demolition Mech
