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

I'm proud that I finished this one, though I'm not used to webdesign itself.

What challenges did you encounter, and how did you overcome them?

No challenges at all. I'm actually pretty surprised it was this easy.

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

Just want some feedback from the mediaqueries. Don't know if they are as correct as possible.
