Digitals - first ever, advice greatly appreciated!

I took digitals for the first time a couple of weeks ago. It was windy out, so my hair was up in some of the photos. I plan on retaking them.

Height & Weight: 5’11.5, 155.

Age: 19

I’m interested specifically in commercial modeling and lifestyle modeling, but I’m open to anything. Any advice on how to improve my digital to be greatly appreciated.
