Looks clean af, but a couple of things.
1. Some of the text isn't lined up correctly.
2. The sections aren't clearly defined. You have a box for the section title, but then create another section to include the body. I'm guessing this is to include the background, but it really isn't needed.
3. The dashes in "- Pricing -" are sorta old fashioned. They're super hard to pull off, and the only times I have seen it pulled off, is when the line is super thin and across the entire screen.
4. Personal preference, then little tab sorta things on the bottom left of the sections sorta tick me off, but I think that's just me
