My biggest advice for young human creators trying to survive in a world saturated with AI: never delete your older works!!! Your older works, even if unpolished/unfinished, show how you improved over time. Your journey as a creator proves that you are human, and that in itself is a valuable asset. It can be very difficult to get hired without a history of older works to back you up. Definitely showcase your best works in your portfolio, but also remember to include a package of older works for your clients to consider!
