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

Figuring out how to overlay icon and color over the image

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

Was difficult to figure out the active state for the big image. but some googling helped to piece together a solution

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

any feedback on the html or css code is welcomed. Is there anything I could have written/structured better? Is there an easier way to do the image's active state?
