You look great with the zero. You are only 3 days growth from a smooth shave basically. You look more up to date. Your first picture was like a 1980's haircut trying too hard to look like someone who is hiding under the hair. This cut or shaved smooth makes you look younger and more appealing, more contemporary. You look much better this way and smooth shaved will not be viewed by anyone as much different from the zero length. I often sport a #1 or zero and most people don't make a distinction, they just say Im shaved. Lately I have been razor shaving every 2 or 3 days because I LIKE it that way and no one says anything negative or different. Plus its fun to do and feels amazing when totally smooth. You will love it.
