Looks simple enough! You've got a rouge closing HTML comment in your single post footer though. Also I think you've got the HTML5 Boilerplate favicon instead of your own.
You're right thanks for the heads up! This is the first WP site I developed so I'm sure there is a lot to improve.
The content looks really solid.

Kinda reminds me of the Addapp app.
In what way?
It's not a bad comparison by any means. Addapp uses lifestyle images with serif text super imposed on them. https://www.dropbox.com/s/g3w7qbef6rhfznl/IMG_2028.PNG?dl=0
