The container for that page looks too wide. Im guessing that it has 100% width, give it a max-width of around 900px to tighten it up a bit for Desktop.
Try giving the ‘WE REACH GOALS’ header text the same color as the bottom-section background and giving it a subtle white text-shadow (text-shadow: 0px 1px 2px rgba(255,255,255,.75);).
Also, the work ‘Opportunity’ has way too much text-shadow. try knocking that down to something like (text-shadow: 1px 1px 2px rgba(0,0,0,0.35); ).
Also, consider giving that signup form a fixed width and center it .
You might also make the login and signup buttons more cohesive… similar placement, similar styling (not just contrasting).
