The photos that you have are great - better than when I was starting out.
Don't be afraid to be creative too. As a seller with small objects like you, I was intimated to be more creative with the space and taking pictures of my items. It took me a while to incorporate different ways to photograph my accessories - gradually working in props to set my buttons or magnets on, holding them in my hand, etc.
Shop photos that are not the thumbnails is a great way to show your product in different styles and backgrounds - some of my birthday buttons have festive polka dot backgrounds, nerdy ones might have a stars background, etc.
I feel that style vs white background because it's an etsy requirement is more important and will get more attention. :)
