Advertising is tough, but here's a few ideas that may help!

Streams are a good way to advertise commissions since you can post new stream announcements (with prices in the description) over and over instead of just spamming the price sheet. Plus many people like to watch as their art is drawn out, so many people are more likely to buy commissions during streams.

When it comes to price sheet I'd definitely tag the heck out of it so that people using the search function can find it easier. Things like "Open Commissions, Price Sheet, Art for Sale, Digital Art, etc." are key words people probably search with.

Having a few deals/sales occasionally may draw potential customers as well! For example some people may do discounted icons for a week, or 25% off adoptables for a weekend, or offer discounts for particular themes they like. People are more likely to buy when they think they're getting a bargain.

Also, coming up with a variety of commissions to offer is always a good thing. I mean sometimes people want something other than a regular headshot/waist-up/full-body. Custom character designs, chibis, icons, pixel "page dolls" of characters, and all kinds of other commission types can draw in people looking for "something different".

Having "themed" commissions seems to draw lots of attention as well. Themes like drawing anthros interacting with their feral versions, fusing/breeding characters and drawing the result, having characters interact with a clone of themself, and junk like that all seem to draw in customers as well.

Apologies about the wall of text. I hope that made sense and/or helps!

Thanks dude! Much appreciated! I do have a Picarto, so maybe I'll start making some use of it soon...
