Just fucking by canvas, brushes and good quality oil paint. You need only five colours[1]. Cost you maybe 50-80 euros. And any mess you produce will give you more joy thanand shot produced by any clanker brain. Keep at it for few years, take evening classrs, look tutorials and you have learned yourself a skill. You can now travel to any majos art museum across the world and have a discussion with masters through their works hanging on the wall.
And you will also see how fucking sad and inferior all these ai images are. Really, trust me, please. There is more to art than this. There is more to life.
