Best with prompts like:
simple:0.8 illustration of a middle-aged woman wearing hiking gear stands at the edge of a misty forest lake, pausing to catch her breath, her face flushed and eyes bright with accomplishment as she gazes across the still water. dynamic composition. style: color planes, (strong inking lines:1.1), cinematic lighting, (hand‑drawn aesthetic), vibrant colors, all in sharp focus
adjust the value for simple to match your taste (and do not like my background too detailed for a graphic novel...)
For me FlowMatchEulerDiscreteScheduler works very well.
Use more steps, if the lining/inking does not look good.
