Nice design. I do have a few suggestions though...
1. Implement a logo or something at the top of the page. White space screams to me "What's the name of the site I'm visiting?"
2. Under the articles page, you could make the titles of the articles hyperlinks so that a site user doesn't have to look for the words "Check it out". That's not a very descriptive link, either.
3. Some sort of system that tells me what's clickable would be nice. I.E. some sort of hover state for your links or even underlining.
4. I see that the stores page isn't up yet. Something that tells a user that the store is coming soon other than a "Please go back one page" with be better.
That's all I have for now...
