Like the other members had mentioned, it's not that bad. There is some recession, but (IMO) you still have some decent coverage.
I decided to crop mine when a light breeze would undo all my handy styling work. That made me the most uncomfortable and I knew i needed a change. In my opinion, you don't look like you're at that place so you could probably hold onto it for longer.
But i'll have to agree with the others as well: it's your hair so the decision is yours, if you can feel comfortable with your current hair then maybe hold off, if you do decide to cut close then maybe go with a short crop (like a 1 or a 2) and then shave it off all together ... i sincerely think you could pull off a cropped or shaved look.
