Mate, you have some incredible art. You really aren't getting the attention you deserve. I have some advice for you:
Join groups. You can find groups by hovering over the "MORE" option on the top of the website and clicking "Groups" on the drop-down menu. Then type in some key words and
join as many groups as you can! Seriously, groups are how you get publicity for your art, and I assure you, your art will get
a lot more attention if you submit to as many as possible. I'm only a member of about a hundred groups, but I know some people who actively submit to thousands at a time. I really like your art and I'm just here to give some advice and help to a fellow artist!
Feel free to note me or reply back to this comment if you need help with anything! Have an awesome day!
