Pot heads

A few months ago I posted a unique plant pot that I made for my peperomia ruby cascade (attached photos). The post received quite a bit of traffic with a lot of positive feedback. Since then, I have made a couple more of the “pot heads” but have not put plants in them yet. I don’t have room for all of them but I really enjoy making them and people really like them (post feedback & I have given a couple as gifts) so I was thinking about selling some of them so that I can keep my creative outlet going without inundating myself with pot heads 🤣
I came here to ask what other plants I should consider using for these potheads? I have big ones and small ones to use so I’m open to using plants of all varieties and sizes. Just wanting suggestions for other plants to use that would be as stunning as the ruby cascade is.

Also any advice on pricing for the different sizes would be appreciated. This will be my first time selling plant pots and I’m unsure of how much to charge (for pots only, not including the plant). Cost of materials for the big pot is approximately $20, and $10-$15 for the medium and small sizes.
