This depends on a lot of factors
1. Notability, just for name alone can fetch you hundreds to thousands of dollars. There have been charity auctions for Matt Groening sketch commissions that have gone for $3,000+, and you arenβt paying for quality art as much as getting a custom drawing from prominent figure. Even a prominent highly followed online artist might have enough pull for higher price commissions
2. Skill level, if you are very high level you will fetch more just for making higher quality deliveries
3. Ability to fill niches. Reason people say nsfw make more bank is because they will do more then majority who will reject it, so if you will do a certain niche people have to come to you, and will pay more because there is no option
So you have to find your worth in drawing and if itβs worth it to you. Really it is what people will pay for your service when thereβs thousands who have them open right now
