Could use some critique - Pablo Picasso Tribute page

http://codepen.io/Loses/full/ENLNZm/ I just finished the First project that Freecodecamp has to offer.

Some things that I would currently like to adjust

I want to set the size of the caption box at the top, my original plan was to put pablo in the middle of two paintings with a caption just for that picture.

This is my first website I’ve ever created, so I would love input from all of you experienced devs!

It’s good, but why have you used so much margin and padding-left in your ul list?

The link at the bottom of the page is missing the protocol. It reads <a href="www.google.com">, should have https: before the www.
And use % rather than px for the margin/padding. Doing it in pixels breaks the design on mobile devices.

How about something interactive for the user. Maybe do something with the dates area.
