Card Making Hobby: Rate/Feedback On My Craftsmanship

Hello, I've been dabbling in making custom trading cards. I've started to make cards for use with D&D. I want to know what people think of them, and if there is an interest in them. I've visited a local card shop who've seemed interested and open to buying and selling them, but I want to know if there is a wider audience globally like making an online store and if anyone has tips/tricks on how to go about social media and gaining a following.
