From the creator:
Paint 2 - is her other paint style, it's also realistic, but supposed to be more smeared also used for sketches, didn't work but the style came over.
Paint 1 - is her more detailed paint style.
Pencil drawing - is her odd drawings with finer but more fuzzy/redrawn outlines, less shaded and not as shiny skin detail.
Bold outlines - is her main Jab Comix style thats more shaded and shinier skin with a reinforced chalk-like outline and less detail on the eyelashes.
Graphite drawing - ??? - Graphite drawing, BAM, who would've guessed?! Her more realistic approach.
