I transitioned from an electric to a straight also but I had some experience with twin blade razors which was of no help at all. You will do fine as long as you don't push the learning curve too fast. I am a little slow so I took about 5 months to make the transition and get acceptable shaves over the entire face.
I did not even try the chin, neck, and upper lip at first. It allowed me to gain some technique and confidence.
Take it slow and enjoy the journey!
