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

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

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

I'm looking for any articles / guidances about best practices when working with image size for different screen sizes. If you could provide some, I would be very appreciated.
