Settings-wise: 20–40 steps, CFG 3–5, samplers like Euler a or DPM++ 2M, Clip-Skip 2... and voilà, let the magic happen!
About V2:
This final version of the kaillustrious series (Illustrious 1.0) better understands the styles.
Also try using different samplers, I have very good results with Restart for example.
About SE:
Versions under Illustrious 1.1 on steroids that I really enjoyed using but which struggles to make "simple" or "minimalist" drawings. Don't go too high in CFG.
