Oh Pam! I know you will master it eventually. From what I've seen, I know you are a piecing perfectionist, and I'm sure you are the same way about your quilting. The samples you show sure look good for a beginner! At least your curves are curvy. I paid good money to have a professional do a quilt top that I thought was a real piece of art, and I think her work was inferior -- not at all what I was lead to expect.
I hope someday I get the opportunity to join the longarming club myself! Hang in there, kiddo!
