It's a chaotic can of worms this one, that needs to be controlled. No easy prompting, do specify about everything. CLIP is using the Illustrious base, so please add stuff like "masterpiece, best quality" to positve prompt, and "worst quality, bad quality" to negative prompt. Don't try real photographic style, it won't work. This merged model does add a bit of realism to the otherwise 2d flat style. almost automatic shade patterns. Has nice sketch or line art style.
