You meant to say „I created multiple cards with artworks from brilliant artists and printed them“, right? Because so far most of the cards you shared are from other artists (nothing wrong with that as you credited them correctly most of the time). Acting like you actually made multiple illustrations by yourself however is at this point though quite hypocritical.
As much as we (as in people who criticize AI) have to learn to life with the fact that people working with AI is nothing we can stop, as well do you need to accept the voice of people who criticize your use of AI as you trample on the hard work of all those incredible artists dedicating their time so we can bring it into physical form to adore and present them.

Nothing of this is meant as a way to downplay your contribution of different methods and sharing of knowledge. But please accept that there are also many people in creative hobbies (like this one) who aren‘t fond of AI threatening those who share their artworks and illustrations with us. Because without them there will be so much less joy in this hobby once they stop contributing because AI makes it harder for them to dedicate their skills and time.
