I don't hear anything too unusual here. Probably decent mic (your choice of LDC or dynamic), decent pre, decent compressor for tracking, more compression and fader riding to keep the vocal where you want it in the mix
sing it how you want it to sound so maybe move up on the mic just a little on the quieter passages to get the intimacy (not too much too kill the sound with tons of bassy proximity effect if you use a cartoid mic) and back off for the louder parts
