Hi,
I think you just need to keep building on what you are doing well already. You have a fab collection of the products being worn - essential for knitwear. Now add some simple, clear pics, I don't even think white background is necessary but just clear.
I have loads of items with white backgrounds which didn't capture the imagination of Treasurers, then I took a pic with a ring and my hand in a fist and got in 3 treasuries immediately, I think it's because it is emotive and tells a story.
For example I love the little owl, maybe retake the pic with him on that crazy brass tree without the note pad and pop that as the thumb nail - very cute!
