Four card feature section

What are you most proud of, and what would you do differently next time?

I'm that i was able to get this site as close to the sample site , it too me a while to figure out the the four cards for the windows view but at the end everything worked out okay.

What specific areas of your project would you like help with?

i have no area in specific but will be open to any suggestions or tip that can help to improve my code
