I live in North Texas and I have a beautiful live oak that provides significant shade in the backyard. I started to notice significantly more leaf dropping this spring, which I read can be normal. However, looking at the tree today, I noticed that there are a lot of browning leaves throughout the tree with some dying twigs. There also seems to be some new growth, but I wanted to have someone take a look at the pictures to make sure there is nothing that I need to do at this time.  
Thank-You for the help!
