Welcome to Folksy. Your art work is so detailed. Great selection. Good luck with lots of sales.
Good luck Nicholas. Love your art, it has shades of David Shillinglaw about it.
As someone who has been moderately successful selling art online, can I suggest a couple of things? You have to spoonfeed people a bit as they will be making a purchase without physically seeing your work, so I would include some more photos: some close-ups, some next to other objects to demonstrate the scale. Some people present them in mock up frames, but you have to be clear that the artwork is being sold unframed. I would make that clear in any case, assuming they are being sold unframed. I would also note how you are packaging them, eg flat, rolled.
Folksy members are very helpful, if you need to know anything, just ask.
Hi there, great work but I have to agree with Chris that it’s best to give as many photo’s and as much information as you can. Good luck with your shop.
