My tools have changed just this year, so I can speak to both phases of my work.
The first wave is how I've done it since 2016 (when I decided to start drawing more often). Draw it traditionally, then scan it, make some digital edits and color the traditional piece via Sketchbook Pro. Eventually, I got a simple screen-less Wacom Tablet, so I decided to start adding in a proper digital step. Draw the pencil drafts traditionally, scan them onto my desktop, line art and color digitally. This would be my process from 2018 on.
First Wave Tools:
Pencils and Micron Pens
Wacom Tablet (eventually)
The second wave hits this year, once I decided to spoil myself with a Galaxy Tab S7 (that and I felt the process I've been working with was too slow and I was not comfortable drawing on something I could see the drawing on. Price was decent too). I needed a screen and man did that increase productivity. Same process only I took photos of the traditional images rather than scan it. 3 months back, I decided to cut the traditional part completely out of production. So my tool list now is:
Galaxy Tab S7
Sketchbook Pro (for drafts, line art, color and tones) (on desktop)
Clip Studio Paint (for text, formatting and additional effects) (on tablet)
Scrap Paper (for storyboards, drafts, concept brainstorming, jotting down ideas, quick references and notes)
Dropbox (moving files from Tablet to PC
Pretty much what I could afford. Sketchbook and Dropbox are free, Clip Studio is worth the price in spades, been using it over a year and I haven't even scratched the surface. Screen Tablet was the right investment for me.
