Is my quality of writing good enough to sell?

I'd love to make some sort of profit here, and I can't draw...

And by selling stories I mean like writing backstories for pets...

Here's a few samples:

Yearn Negligence Stump

I read Yearn's story and really like the images you put in there. I think your writing style could sell depending on how much you charged and how long the story is.

Sweet thanks!
