These look great! I have been taking product photos for a while now and here are some suggestions. In general, I think the first thing you need is to think of high level photo categories:
1) Product photos for e-commerce/website/Etsy etc. - Ideally, these need to be close ups that clearly showcase your product in thumbnails while customers are browsing through online. I love blacked out backgrounds for my photos, but white is the most popular. A lot of folks take pics against rustic wood/brick type backgrounds as well. There are a ton of background options available on Amazon, Michaels etc. for as little as $20 if you want to experiment.
2) Pictures with props - Props will really help your pictures stand out. I sell a Bourbon & Oak shaving soap and one of my pics is the soap with a lathered up brush, safety razor and some lovely Bourbon in a nice whiskey glass. My Sweet Tobacco scent has a "pipe" as a prop. You do need to be careful with props though, your customers will associate your product with the prop, so it can potentially backfire if the prop that you choose does not "jive" with the product theme
3) Lifestyle pics - This is where you can experiment with perspectives, lighting, shadows etc. Try to take a portrait picture of your products, any backdrop will do really, you do even do this outside if you have the time. Hopefully your cell phone has a portrait mode, read a bit about "bokeh" and best practices around portrait photography. Change the perspective so that you place your camera horizontal and closer to the product. Let sunlight fall on your products and take a picture with natural shadows. Be creative!
There are other themes that are possible, but these 3 will allow you to build enough variety and good quality pictures.
The next thing is lighting, and boy, I can take the whole day to talk about just that. My recommendation without overwhelming folks that are just starting with product photography is to build a simple lightbox at home. You need a utility knife, tape, a medium size moving box/carton, some tissue paper to build this - total of may be $15 worth of investment. Ton of Youtube videos out there that show you how to build a lightbox. For lighting options, you can either re-use your table lamps or invest in some cheap lights, you really don't need this unless you have enough scale to warrant this kind of investment(time, money and space). If you don't want to do any of these, there are companies out there that will happily take your money and sell you a well made lightbox with pre-installed lights, these are convenient for sure, but personally I think they are a bit of a rip off.
Also, read a bit on composition. This is a whole another topic in itself(and my favorite actually), but I usually recommend familiarizing yourself with the rule of thirds, a very simple concept that everyone can incorporate to get their pics to stand out a bit.
Lastly, I think a lot of folks undermine the importance of editing. You don't need to be an expert, shoot RAW and edit in professional softwares like Lightroom, Capture One etc for this. I still take a ton of pics on my iPhone and edit them on the Photos app on my Mac. Editing is what will make your image stand apart from the rest of the crowd!
Hope this helps a bit and feel free to reach out if you have any questions.
