At the start of it all years ago - I was an illustrator. It took too much of a chunk of my effort and energy, so I pivoted to graphic design, UI. I now offer illustration as a special add-on, as a "want" not a need; as something that you buy when you want that extra feeling of hearty and authentic. Nowadays you can download any illustration imaginable, so once people get tired of AI art, you'll notice your clients seeking authenticity, imperfection, joy.
