Remember to stretch your skin as tight as possible and pull it in a direction so they whiskers stand up, not lay down flat.
I wouldn't strop on the first shave, you'll most likely strop wrong and dull the razor, everyone does this at first.
Make sure your shaving angle is steep enough to cut hairs, too low and it'll cut nothing.
Use as much pressure as a feather would landing on your face. A DE and a straight is a light and day technique difference.
