Hi Andrew!
I looked at your stuff and its wonderful.
I can't speak on the price points (since I'm not an artist).
But Etsy is a good platform to sell your stuff on if you meet people off of Etsy who want to buy your work, since you don't have to build your own site.
For promoting on Etsy, you will need to work on your tags first. The link will take you to a team that specializes in SEO (
https://www.etsy.com/teams/11352/relevancy-and-seo-for-all-etsy-shops). You want tags that match your titles to get people to find you in the searches. For instance, for this one, the Title you might want would be "Grabby Hands, Metal Belt Buckle, Upcycled Steel, Steel Belt Buckle," Than have your tags be, "Grabby Hands, Metal Belt Buckle, Upcycled Steel, Steel Belt Buckle, Men's Accessory, Upcycled Accessory," etc. Make your tags multiple words to capitalize on the searches.

You might want to pick one or two social media outlets and work them. I personally use Instagram and Pintrest the most and occasionally (like twice a month) my twitter and fb.
