I like to see products in settings that evoke a "tone" of a given piece. So if I'm looking at a Tarot reading, a discreet quantity of "mystical" items beside the spread would help get me in the mood. If I were looking at earrings that were modern, I'd expect clean lines and bright lighting; if I were looking at a Renaissance-inspired pair of earrings, I'd expect heavier colors and more richly textured backgrounds.
The more different pictures you can take of your piece, the more of its "story"--and I'm big into product story!--you can tell. Just like if you sell drills, you don't actually sell drills--you sell the hole--sometimes it's not about what makes your piece different from someone else's, but how your piece makes that customer FEEL more distinctly and positively about themselves that encourages sales. (Whoa, long sentence, sorry!)
If there are different options available, too, using at least one of those photos to show off the options is fantastic. (People like customization, even if it's just a choice between two metals or something.) I have four decks that I regularly use for readings, so I took a picture of the Fool card from each and put them into a collage for the last image on every listing. That way, people can pick the deck they want for the reading! I've gotten some great positive feedback from repeat clients after I added that option.
I also filter EVERY ONE of my pictures, and I know that makes my photographer coworkers grit their teeth. I don't have time or expertise to tweak in Photoshop, unfortunately, and filters really do work to brighten up colors and make the picture more appealing. One day I'll be good enough to #nofilter, but it won't be anytime soon. (I'll prolly hire someone for pictures before then!)
For your photos, I love the richly textured wood behind some of your products--makes me think "Old house that maybe might be haunted," which fits your store name and theme--and the odd paneling-floor behind the voodoo dolls specifically.
I think you might have fun with some "spooky but cute" props around your dolls in the future, and maybe switch up the locale. So do two pictures with that "basic" wood paneling to show front & back, then maybe two more in a different setting. (Outside? With other "ordinary" dolls to be extra spooky? No idea.) The last pic in your lineup, though, I really truly think should be all three dolls of the different colors together, so someone can see what you mean by "green" or "red." (Is it forest green and pinky red? Or is it blood red and mint green?)
I hope this helps! Great question.
