Text line height isn’t consistent. That’s the only issue that jumped out at me. The bottom boxes look right, some of the other text area look a little squished.
Aside from that, it’s a hot little landing page.
Hi, Check also alignements in the top part (ie : logo, big title, text, list, buttons, would look better if all aligned left). I see also vertical spacing issues (ie, less spacing within blocks at the bottom – EAsy to use, etc… , so they look more like a group).
Maybe keep the oswald font for all the bold big title, and the other font for text. Looks like there are too many different variants of the 2 fonts (size, uppercase), with no clear visual hierarchy.
“Instant Access” and “Sign up now” are fighting for attention. Why not mix them inside a big button or use only 1?
