It's duable for a beg to get a decent amount of income, but you will need to do a few things
>get an appealing art style to give clients a reason to buy you draws
>find art friends that unironically like your shit to help you grow in both skill and popularity (and maybe commission you too)
>play social media right with basic digital marketing and being part of your art circles with charisma
I got people seething due to the fact I have a decent income and feedback as a beg that barely understands the fundamentals and I could be getting more of each if I wasnt such a lazy fuck to practice that's also being eaten alive by irl duties like work and college. Truth is my beg tier skills are only one bit of the whole effort that has put me where I am
Mind you, this is not an excuse to not get better at art, you will have to go further to reach more. So you better start practicing and and stop being a permabeg
