Definitely. There is a chance that strict pressing makes the situation worse, if you start to rely on strength instead of timing.
As Koing said. Film yourself from the side, and check the alignment. Personally, I lower the elbows when jerking, so hips, elbows and wrists are straight under the bar. Some jerk with the elbows high, but I never had that working for me. Also, check that the bar stays in the same horizontal position through the jerk (i.e. don't go forward.).
Also. As far as I'm concerned, the jerk is the most timing dependent part of the lifts, so work on it 'til you puke. Set up a timing "measure". I.e. "when the bar reaches the peak point, I will be fully lunged under the bar." That is your goal. You can use the push press to practice timing, but doing the actual jerk of course has most carryover.
Also, if you're serious about olympic lifting, never lift in front of the mirror. As soon as you start looking, you stop feeling.
