Did I make a plumbing drain mistake?

My intent is to move a vanity to the middle of a wall in a 5 x 8 bathroom. The supply lines did not require any significant modification. I simply replaced the existing galvanized pipe with shorter pipes to get it where it needed to be. The drain, however, was a little more challenging. Taking the sage advice from one of the old timers at my local hardware store, I made the drain modification you can see in the accompanying picture that incorporated a 22.5° connector vertically. Will this set up siphon my P-trap?
