Trying out shaders in Godot

I've decided to work on the artworks in the game. I saw some shader effects in the demo projects of Godot. I particularly liked an aura shader used there. I'm applying that to the stick now. I think I should go with this theme.

UPDATE:

The aura shader didn't work out well. The image should have alpha portion for this shader to have an effect. This will complicate things. I want  this project to be as simple as possible. So right now I'm trying another shader which has a glow effect. I don't think it will look any good with my current monochromatic art. I should change the artwork slightly.
