Adsense is getting stupid day by day.
I don't see any reason to not accept your blog, while there are many low-quality sites that have at least 100s of ad units placed around the page easily get approved by Adsense.
The design is wonderful, minimal and content focused. Writing style and content are also good.
Maybe your side menu might be overlooked easily where your About page lives. Consider moving About page link to the main menu.
