Thanks. That actually helps a lot.
All the bondage!

I think one of the bigger problems is that multi-spot commissions are harder for people to want or afford. In addition to the price increase, it means they either need a friend/lover to go in on it with them, or have multiple characters of specifically those assigned genders. (which is harder in a community that loves things like c-boys/herms/dickgirls)

Also I recommend not making your base so pastel-colored when advertising. It makes the contours of the actual characters harder to make out, and generally is less appealing imo.

But the biggest problem isn't one you want to hear, it's that you're making isn't in demand. There are a couple of ways to solve this, as the person above said, appealing to a fetish community, but you have to look at what you're doing overall.

Your gallery is filled with ych opportunities with no takers, why is this? Is it because of the prices, or because of the quality? It's because of the quality. With things like chibi-in-a-bubble commissions, doing quick flats is acceptable. With anything more than icons, you need a higher level of quality... one you haven't displayed at all in your gallery. The two or three pieces with shading are still lackluster, and look completely flat. You need to take some time aside, do some art for yourself that you would be willing to put in a portfolio. If you want to make money off of selling art, you have to treat it like a job. If your yelp review says 1-2 stars, you need to improve the quality rather than change the menu.

Sorry to be brutally honest, I know criticism is hard to take, but I think it's by and far the best advice I can give you.

Thank you for this. I'll be sure to do some personal work and put a good amount of time into it. Would you mind if I note you for a crit on some pieces?

Of course, anything I can do to help. Feel free to add my skype too if you want. It's Aimlesswaves, like everything else I have.

Thank you so much
