I always find it fascinating to hear about how others plot out making their comics and art.
I start by editing a chapter of my original script for the comic to include dialogue and edits for any new story nits I need to keep in mind.
I then draw out each page in a small rectangular thumbnail to give me an idea of how much I can fit on a page that will be legible.
I'm terrible about remembering where to put the text bubbles as I draw more thinking about illustrations than I do thinking about graphic design (something I need to focus more on so that my text and art can work together and not against each other).
I then take a picture of my thumbnails and import the photos into Procreate on my iPad into an 11x17 350dpi page and do rough line art. I'm working to do nicer roughs so I can cut out this rough lineart phase and move to do clean lines from the thumbnails, but for now, I have the roughs and then do clean lines on top.
I tend to do background elements later than with the characters, so that's another thing I'm trying to be more aware of so that characters and background elements work together over looking separated. I notice that when I have background elements pre-drafted using Planner5d It's easier for me to do this, But drafting cities is a lot of work over drafting a house or room XD.
Afterward, I block out my flat colors based on the character color swatches I have and scenery (if any). I make a layer and clip it to the flats and then do my shading and highlights.
Lastly, I do my speech bubbles. I was doing them all in Procreate bc they added text options, but I am going to go back to using Affinity Designer for this bc they have lovely text editing tools that I think will look better.
Once all that is done I save the page for web viewing and boom!
I prefer to work in batches, so a chapter at a time and get them qued up before moving forward to the next set :D.
For avoiding burnout I just work on scheduled days and make sure to have things to look forward to like a specific scene, or having other fun things planned through the week, but I truly love making my comic and look forward to my comic making times, but sometimes you just need to take a break so that you don't burn out if you feel it coming.
