Hello there, so I am Shan and I can tell you from 4 years deviantart and alot of trying to raise points that there might be a few reasons for this. But that your watchers hate you won't be one of it, believe me :3 First of all I am not popular, I am a decent artist that tries to improve over time. From what I know, making money/points on deviantart is a tought bite, most people here are kids around 13 or 16 with no credit card or paypal, mom and dad won't pay for everything so they can't afford higher prices than maybe the 5 points they luckily got by a donation or giving someone a llama via the trading tool ( or however it's called XD). But with more watcher you'll might get 2 or 3 that are already 18 or 19 maybe even older, who have some money on their hands and can decide what to do with it. if they are pleased with what they see they will buy it. So I can't tell you a way that will definitely work out so that you get more watcher or more moeny/points, but i have some tipps that might help you.
First you should stop thinking about making money. Sure it would be cool to make money right away but sadly that won't happen on deviantart unless you have a super famous friend who promotes you non-stop. The time you need for thinking about it could be used for things that are more fun and make you happy instead of depressed because what you want won't work out. :3 take that time and draw something, cause the next tipp might sound easier than it is.
Improve by drawing things you didn't drew before, play around with your art style , the way you colour in whatever way you can think of, like I said people buy artworks they like or more the way, they buy art from people with an art style they like. I looked through your gallery so that I can give you these tipps right here and I can tell you that your art might be still in that beginner stage but if you keep working on it you will see that it will change soon and that you will improve. The first 5 years of drawing are full of improvement, since you'll learn about anatomy , how to work with your tools and programs. If you take a look around you might find tipps and tricks for those tools and after a while you'll get so damn good that people will look up to you and even ask for artworks 8D
The next thing is ask people for help and critique, sometimes you don't see the mistakes but others do and with a honest critique you can erase those mistakes alot quicker.
These are things you can do to improve with yourself but to get noticed I only can tell you to uploade your artworks into groups, talk to people, comment on artwork, send llamas and do some requests from time to time, cause free art always brings the people to you :3
Hopefully this will help you a bit QwQ" Have an awesome day and don't let this money thing drag you down!
