you have a great skills , that work of art is very professionally made and no doubt that you are a gifted person.

But selling for 18 hundred Dollars for a single painting is too expensive for me, that price can be for those Named artist as i have seen some paintings that worth 1k usd and that's already good.

But of course i am just sharing my thoughts as i really love your Work here, Hope you'll find deserving buyer ASAP.

Good luck !!!!

I wish I also have a talent with art. For me as along as you have skills or talent to offer, you can earn regardless of the means of payment. Maybe you can just ask someone to pay you in bitcoin in exchange of your art? Would it be too much to ask to see some of your art works?

Hi OP, your  art is great , no argument and I’m sure it will sell. I presume like most artists it’s all about getting your artwork seen.
Here are a few suggestions to help
As other members have said , the collectibles section of the forum is a great area for sales and many artists sell here -
RYR
1Dq
Corrosive Creations
Baraded
It may be worth reaching out to them personally to see if they can offer any advice.
There are also a lot of collaborations going on between artists and collectible makers and this may be a route you could look at .
Also , the NFT world is really taking off and digital art is becoming more and more popular . Have a look at these websites-
open sea.io
knownorigin.io
superrare.co

Anyway hope this helps and good luck  

Do it like how Pascal Boyart does it. Create great art(Bitcoin related or not), and just provide a donation address. If people like it enough to give you some sats, they would. It's worked really well for Boyart because his art has reached trending in other Bitcoin communities.
