Draw a large dark circle or oval for the black hole center
Add a thinner glowing ring around it for the accretion disk
Sketch curved lines spiraling into the center
Make the center the darkest area on the page
Shade the ring with bright colors like orange, red, yellow, or blue
Add light streaks or particles moving inward
Blend the edges of the ring to create a glowing effect
Add a subtle halo around the black hole if desired
Darken the surrounding space with stars or a starfield
Erase or soften parts of the ring to suggest distortion
Use contrast between the dark center and bright ring
Finish with smooth shading and clean outlines
