Need advice on digitals before submitting to agencies

Hi, I’m totally out of my element right now but for the last few years I’ve been told that I should consider going into modeling and I’ve finally decided to take a chance and try it out. I live in Alabama and was going to try submitting my digitals to agencies in Atlanta, but before I do that I would like some advice on how I can improve my digitals. These are my first ever digitals I’ve ever taken so sorry if they’re not very good haha. Also I was thinking of redoing them with my afro so they can see my natural hair but I don’t know what recruiters prefer. I will attach a pic of it at the end. Any advice would be greatly appreciated!
