I've managed to actually shoot some pics of my painting progress. This is the process I used to paint the flames:
First a mask is created. I use a pencil to draw the flames' shape, then use my Xacto to cut it out. I'm using standard 3M blue tape.

Then I apply the mask to the pieces. I'm painting the flames themselves, so I apply the mask that is NOT the actual flames.

Next, I paint. I'm painting your run-of-the-mill yellow/orange flames, and my technique is very similar to preshading. I basecoated the flames white, so the yellow will be nice and vibrant. Then I lay down a coat or two of yellow. Next, I shade the tips and edges of the flames with orange. Yellow is then applied to blend the orange more smoothly. Once done, the mask is removed. This is the result.
