What do you do when

you try to draw something for others to use (a lineart, or an adoptable, etc) and you just love it too much to let others have it D:

I'm trying to make a new lineart, of a cat couple, and maybe some kittens too! I've got the female almost finished and I looove her pose, almost too much to use as a lineart.
Is this where you make a pay-to-use lineart? 
But how much to charge?

PS does anyone wanna see it? I can upload to my stash ~
