You are off to a good start! That smoke effect is really cool!
=> Should Devises be Devices?
=> On some products you link off-site to other eCom sites?
=> No social media?
=> Personalize the About page with photos of your staff.

I have not noticed that @Muse, can i ask which items are they, so i can fix them, not my intention to link them to other sites.
Thank for the help!
