Designer here. I'd add more leading (line-spacing). More spacing between sections, too. It needs to breathe. I'd drop the exclusive use of grey and use black for the body text, at least. Grey might look nice on your screen because it's very bright, but not everyone's is, and when printed, can look washed out and like a mistake. Contrast in body text is good.
