With that being said, there's really not a lot of options for precise look direction control. Reliably working stuff is basically limited to: * looking at viewer * not looking at viewer (sideways/aside/away mostly have the same effect) * up/down
So, you'll have to get creative to get something interesting out of the model. See how We can make Twilight look at her own nose by combining `looking down` and `cross-eyed`? ~Silly Twiggie.~ But getting what you want out of the model isn't just about what you put in the prompt, it's also about what you don't put in the prompt. See that second picture in the last row where Twilight is looking away from the viewer? Notice the absence of any `looking` tags. That's because as soon as the model sees "looking" in the prompt, it immidiately goes "Aha! Eyes must be visible!"*. Figuring out each model's quirks and biases is not easy and is often incidental, but it's just something that We have to deal with.
So, in conclusion, it kinda goes without saying, but most of the time it's just way easier to manually draw the roughly right irises' direction and inpaint, otherwise it's just begging the RNG until you hit jackpot. Note, that, although I'm using ZoinksNoob, a lot of this information will translate seamlessly to PDV6 and its derivatives. Anyway, hope you find this interesting ;)
