What you'll probably realize with 4x5 and LF in general is that wide shots can be done with ~zero distortion. So it's fun to get a crazywide and just enjoy the possibilities.
Which lenses are you using for MF? Hold one in front of your 4x5 and you may be amazed. Among my recent exploits, I have been using an rz 110/2.8 on 5x7 at close focus. With LF you can use all kinds of nutty lenses... or pinholes for that matter. Just have fun with your new format!
