@JohnBitCo, you may try setting up an Etsy shop
[1] to sell your digital artworks. However, you will need to put in a lot of effort in order to build your digital shop since merely uploading your artwork and stuff and waiting for people to come in will not work.
To prevent any problems, make sure to add information in the product description that informs consumers that you are selling
DIGITAL artwork rather than traditional drawings. Or if you want, you may also use another option of 'dropshipping,' which allows you to distribute printed digital artworks to your consumers.
In terms of bitcoin payment, you could just include a 'Other' payment option that notifies customers that they may purchase your items using bitcoin. However, if you are not using a bitcoin payment processor, you must contact the buyer directly with your bitcoin address and wait for the transaction to confirm.
