Just some observations:
I agree on needing some contrast on some of the photos. For example:
- the cowl stands out because the mannequin blends with the bricks.
- everything is a little too close in colour. Maybe you can get a large coloured bristol board to put behind? A neutral grey?
Also, you need to sell the product more in the description. Is it indoor to go over a shirt? Especially a deep neck? Or does it just go under your jacket as an alternative to a scarf? How do you wash it? Is it hang dry only?
Maybe you can fit more keywords in your store description?
This line, right near the top is really good:
Knitting or sewing clothing and accessories is my true joy. Knitted items create a simple, easy-wearing feel...
Use an alternate to "knitted items" somewhere like "knitted accessories" or "knitted fashion" maybe?
Good luck with your business.
