Art pricing help?

I used to have an art shop on other games, but I've been inactive on them and since I just got here and I'm still excited about it, I thought that selling art might be a good idea to jumpstart my pack. However, I'm not sure how pricing goes around here, prices seemed to vary a lot from the shops I visited so I guess I should get some input directly from people who would be interested in buying or other artists.

I'm going to link some of my canine art, some are more towards sketches and some more fine lined flats, which I guess I'd probably charge differently? It's been a long time since last sold art (or even made anything for myself) so I'm honestly a bit lost. These are older but my style haven't changed a lot.

Also not sure what people are more interested in around here, but I can also draw other animals besides canines. Some people might know me from other games.
