any tips for helping CW drawn in procreate to look more cohesive with the site's art style? does anyone have a preset or custom brush used in procreate they use for lineart? i'm specifically having a hard time with the lineart/shading! any help is appreciated.

I use a Soft Airbrush for lines. You can find it under Airbrushing. I reduced to size to 1%, or just barely to 2%, somewhere kinda inbetween there. You may find that you have to run it over some areas, because it can be thin, but it has given me the best results.

For flatting and shading, I use the default Studio Pen under Inking. At least, I think it's default. 6-7% size. It's very good for the cel-shading look and covers a lot of ground in a way that just using the Soft Airbrush would not.

it's you, my guardian angel. i was worried nobody would reply. your kindness will be repayed to you for this. i will give these methods a try and renew my determination to make something great! thank you :)
