I'm designing a controller based on Hanzo from the game Overwatch. On the back of the controller is going to be his Ultimate move which is twin spectral dragons that fly across the map and deal damage to anyone it touches. They're blue and have a glow like effect to them, so I was planning on using this image, and wanted to make it seem as though it's glowing. My wife has a cricut, that I plan on using the create a stencil with, but I'm not sure how to apply the glow effect after.
