Can you check my landing page?

Hey, David! Great start. Some rough visual design thoughts:

• Try to normalize all of the layouts and content a bit more. Lots of layouts and lockups are increasing the noise.
• Try fewer surfaces (example: the boxes around images)
• Less type variation. There are a lot of sizes and colors as well as the images. I'd move more into a matching typeface. Pick 2 sizes and use space, dividers and subtitles instead of the additional hierarchy. Doing less with type in general usually helps.
• Images are stacking at smaller screen sizes and become tough to read
• Watch the line lengths as the copy gets hard to read. There are a lot of typography resources around how to pick the length online, but I'd stick with about 50% of your current max-width.

Hope that helps.
