I’m baffled by your remarks about sketch-to-image. Maybe I’m missing something in what you mean, but sketch-to-image, to various degrees of completion (that is, it’s more than just sketch-to-image), lets you guide things in a way that prompts simply don’t. It’s rather useful if you’re trying to compose something specific, and plenty useful in other scenarios too.

Does sketch-to-image make sense? Um… yes? Absolutely? I genuinely don’t understand how you could even deny it, let alone act as though that’s the obvious answer?

Am I misunderstanding something of your meaning?
