hair styling

Should I shorten the part of my hair marked in red when I want to grow the hairstyle in the photo? maybe it's better to grow this hair out? I'm having trouble tucking this hair behind my ears and I'm not even sure what I should do.

I’ve been asked to cut and style a clients hair for a fresh new look. The hair is very thick (straight), and the client has a round full face and is in her late 20’s. Her current hair is long with some longer layers around the face. How would you cut and style thick hair on a round face…ideas...
