There is no problem unless you insist on reflecting what you had in mind exactly. That needs minute controls, but no matter the medium and tools you use, unless you're doing it in your own quest for artistic perfection, the economic constraints will make you stop short of your idea - there's always a point past which any further refinement will not make a difference to the audience (which doesn't have access to the thing in your head to use as reference), and the costs of continuing will exceed any value (monetary or otherwise) you expect to get from the work.
AI or not, no one but you cares about the lower order bits of your idea.
