Hi,
Congratulation for your online store. 
I have feedback regarding below points.
[1]. The speed and website need optimization like resize images,gzip compression as per suggestion from gtmetrix. Attach screen shot.
[2]. The shop logo is small in size.
[3]. Lot of empty white space in top sliding banners . This can be utilize for branding and product showcase with big high quality images.
[4]. We can fetch as bot in google webmaster tool to improve ranking and visibility on search engine.
I hope my suggestion helps.
