Some formatting questions

Hiya,

Really like the theme so far but have some questions that I’d really appreciate your help with.

The site I am working on is http://www.aligolds.com.

1. How can I make the text ‘Hi, I’m Ali Golds’ not just upper case but upper and lower case?

2. How do I get the ‘Learn More’ button (with the second image) to be in the middle?

3. How do I get the images to fit on the screen on my mobile?

Thanks so much (in advance) for your help.
