Text to vector graphic (beta) is practically useless

I'm trying to get this feature to create variations of an artwork for me for a logo design project, but no matter what prompt I enter, or what artwork I ask it to reference, it will give me the same style kind fo stuff.

I want a black and white woodcut and/or line-style illustration of a bird – here's a full-colour cartoonish bird. 

I want it to reference an illustration of a bird in the style I've described - here's a bunch of birds in the same style as before... 

Am I doing something wrong?
