Welcome to the forum ! You're not really a lurker any more
Great first post.....asking questions always gets replies.
Also, thanks for telling us something about yourself.
Another suggestion on watching your back cast : keep your left foot pointing straight ahead, as you normally would, but turn right foot 90 degrees, so it points to your right. ( assuming you're right handed ). It makes it much easier to watch your back cast develop over your right shoulder.
Take a look back, make a few normal casts with both feet forward, check the loop as needed, but don't get in the habit of the " observing stance "
Post often, and let us know how you're progressing.
