I love them!
The #4 pic doesn't look noticably blurry to me. I have a hard time seeing #5 on my laptop but it's ok with a regular pc screen. Just an fyi. I don't think it would effect anyone but me here but since you're targeting hpmini audiences as well I wanted to tell ya lol
Just a screen difference.
I would def use all of the photos. If there's a question about blur etc like posted here it can quickly be cleared up with an additional product only shot. All of these are top etsy photo worthy.
I love the bkg and how the accessories pop for view in these.
