Final touch on Shopify store

Hi - I have designed and vetted up my Shopify store cosnetic.dk (password "mads"), but I need a final touch to make it more clean, good converting and custom. It needs to fit in to the beauty universe - the design has to have a Scandinavian touch and hit the target group women 17 - 30 years.

I'm not looking for a complete redesign but some final touches.
