no need to be sorry~ i posted a tutorial a while ago, here! the thing with the screentones is not covered in this tutorial, but that’s basically just applying patterns to the image.
here are my steps in photoshop after i made the screencaps black and white. sometimes the images come out really shitty after you used threshold on them so make sure you have the original cap open somewhere, it will help you with redrawing and adding the screentones ?
