Hey there. Things on these forums are kind of slow, so don't expect an answer right away, but all topics will probably eventually get answered.
Regarding your store, I personally don't like the theme & logo, but that might be just personal preference. However what I did see, which could impact you negatively are a few words spelled wrong. For example on the FAQ page is says you offer FREESHIPING. It's 2 words and shipping with two P's. Anyway, minor stuff like that, but it does matter.
Your theme does need a bit of polishing. For example on the homepage, if I am scrolled all the way down, the page scroll flickers a bit. Also your newsletter signup form has a bad color scheme (it's hard to read the text on the signup button).
Maybe rename the "news" menu item to something like "more" (about us and get in touch isn't really news), and move it to the end of the menu. You want people to see categories first, and see that "more" menu only if they actively look for your blog or about us page.
Other than that, if you've validated your niche and know that you can make sales, everything looks good to me. Please do note that I'm a newbie myself, as I have yet to make my first sale. I do know a few things about websites though.
