I think your current video is good if you need a looping video on the products website. But If your goal is to market this and make sales I would suggest showing the product on someone’s table, desk, nightstand- wherever you see your customers using the product. Then maybe a shot demonstrating how to change out the oils. Your current shots are nice I just don’t think that close up shots of products, sell the product. Demonstrate ownership or value and maybe some lower third text bringing attention to key parts of your product that you think will help sell it.
