being an artist is basically just sacrificing all basic human function for indefinite periods of time to put stuff on other stuff.
Traditionalism is usually the way I draw so it’s alot easier to add detail compared to digitally at least in my opinion, I work with a large surface area, and small sized pen tips (01 and 005 are all I use the majority of the time) and I have a few white pens to go over and correct and highlight areas. but I do use photoshop or sai to clean up mistakes if I need to or add details and gradients that were lost when I scan my work.
When I do use a program to draw / correct what I’ve drawn (sai is usually what I use) I use a large canvas and the line tool, helps keeps dots and lines consistent and small details can be added easier. It usually takes several layers of white (or whatever the canvas color is) over the ink color and then repeating my shading to get decent gradients.
