What works best for me:

- weird fingers, wavy arms/legs forms, twisted forms;
- ink blots, dry brush shading with black ink
- dirty walls and floors
- dry brush/pen hair
- very thin nervous pen lines + thick dirty lines made with a brush;
- parts filled with black (eg black suits, pants etc.)
- empty areas in the image
- dry brush tints (arylic, watercolor)
- brown ink/ or ink of any other color together with black ink
- pale acrylic backgrounds

------------------------------------------------------------------------------------------

- characters should be like me, act like me, have similar mimic;
- not more than 2-3 colors in one picture;
- uncertain characters with faces that make me smile;
- grey shading;
- lots of detail in one place and a blank field in the other.
