Hi Kevin:
I think you should narrow more your audience, i mean, woman between a range of age living in a wealthy are of Germany is a wide audience. Try to look what kind of interests do they have, likes and dislikes...
If your competitors are selling the same products with the same price and shipping time, you will need to get better from other ways, try writing a blog (it has an amazing potential to drive organic customers to your store and helps with SEO!)
And talking about SEO, i have made a Shopify stores SEO guide, it contains some really nice information on how to improve each part of your shop.
