Well.. It's your hair, so I don't want to tell you what to do, but if it were me, I'd continue to let it grow. If I cut my hair that short, it would look exactly like that picture, and while I think it looks good on her, it's just not for me. Even when I was growing out a straightener, I couldn't bring myself to cut my hair off. I'm growing out highlights too, and I've just been getting semipermanent color to cover them up. I think if you're taking good care of your hair and get regular trimlettes you should be okay. If you're uncertain about getting your hair cut off, I wouldn't do it or at least think about it for awhile.
