One other comment, I'd agree with what Toymaker said about the 45 deg up line at the end of the box looking too steep. I practiced this on my on for a few weeks and when I finally went to a field with experienced pattern fliers one of the first things I was told was that my up-lines weren't steep enough. When I adjusted and did as they instructed I was shocked at how steep it looked. I still don't know exactly how steep to draw those lines, but I'm closer than I was

Actually, I must correct myself, one of the first things they said was something to the effect of "Hey dummy, fly straight". OK, they didn't really say "dummy" but that's how I felt
That's why it's nice to have some experienced pattern fliers to fly with
