Many of the parts are optional
Idk what to say tbh..
Before

After

Few notes:
- remember to keep size of the drawing as canvas size
- "brightness" sometimes doesnt work - Make new layer, use any color you
want (depends on if you want darker or brighter effect. For dark - darker color, for bright - brighter color - I used here dark blue) set layer to "brightness" and change opacity as you like.
- "line color" and "line blur" is for lineart. Remember to keep one around. If you don't have one, you can skip this action or:
- copy layer with the original drawing
- make correction layer with saturation and set it to 0. Marge it on this copy
- make correction layer "lever correction" and try to move around till all it's left is lineart
- use "line effect" in auto action, but set it to "screen" and merge
- now use "line blur" and all is done : D
I also reccomand "Retro TV Frame" for even better effect!
But that's only optional (for example I didn't use it here)
