|  | Start with your background colour set to white and foreground to black and using the radial gradient make a circle like this | 
|  | Apply stylize/glowing edges with edge width=8, Edges brightness=8 and smoothness=2 | 
|  | Now apply stylize/find edges | 
|  | Make a circular selection, invert it, and cut to make it more round | 
|  | Now apply brushstrokes/ink outlines with stroke length=38, dark intensity=10 and light intesity=10 | 
|  | Apply stylize/diffuse and set it to anisotropic, that's it. | 
|  | With a bit of tweaking it looks pretty nice, i just altered the hue then brightness/contrast, deleted the middle and put it on it's own layer, bit of dropshadow and placed it on a texture |
