I probably do my comic in the most inefficient way possible to be honest.
First I go over the written script and the dialouge and make a rough layout of the panels and start to sketch what's in them. I draw traditionally on A4 paper with my pencils and do a really, reeeally rough draft, where I already place the speech bubbles (even write the text into them, to see if it will fit).
I then go from panel to panel, working out the details and going over the sketch with a pigment liner, pretty much changing between drawing and inking. I also leave the speech bubbles in and draw them by hand. So far so good. Now comes the ineffecient part: I use watercolors to color my pages. Coloring and shading is done in one go, but I have to wait for the colors to dry up. The colors I use however tend to cover the lineart, so I need to go over the whole page again or it will look like a smutched mess. I tried to color the pencil drawing, but it never came out as good. So yeah, I do two linearts for one page.
After that I scan my page and go into digital editing. I use a Wacom tablet and Clip Studio Paint. First I clean up the page. I go over the whites and blacks as well as colors, that the scan faded out. I recently started to also add digital shadows, because the scan would fade out the ones on paper. I also like the higher contrast of the shadows more this was. So adding shadows is the second step. After that I just add the text into the already predrawn text bubbles (using GIMP) and that's pretty much it. Takes about 6 hours in total.
This is how my edited pages look today:
This one is older. And while I still really like it, I will probably go over the old pages, just to clean up the white borders, because they look pretty dirty ^^ (Also, I used Comic Sans. What was I thinking?)
