Someone asked if i could share the settings i use for lineart/coloring. I don’t use anything particularly fancy but here they are.
I use a hard round brush with size jitter set on pen pressure for both lineart and coloring. I also use a hard round brush set on low opacity and transparency set on pen pressure and a soft round brush set on low opacity.
There’s not much explaining to do since there tools are extremely basic. Photoshop can be a jerk when it comes to lineart so you can always experiment with SAI or Manga Studio as i’ve heard those are a lot friendlier in that area. Also practise using long, fast strokes and don’t be afraid to abuse Ctrl-Z and do lines over and over again until you get them perfect.
