Solid layout overall. I love the theme buttons at the top both as a design element and for the functionality.
While I like the use of text justification from a bird's eye view, I'm not fond of the actual readability in narrow columns like you have on the front page. Since you're also the site editor, you can mitigate this somewhat with careful word choices, but I already see a few lines that look odd to me.
Your paragraph spacing on the home page creates an uneven vertical rhythm between the columns. If you make it a multiple of your line-height you can enhance the unity of the design and let it breathe a bit more. (try a p margin of 1.5em to see what I mean)
The line height in your headline text is very tight. This can work for a short sentence, but for a full paragraph the covers the entire width of your site, it gets tiring.

Thank you very much, I'm going to look into adjusting the headline text and paragraph spacing. Again thank you great feedback.
