This is the whole back of my Aran coat after I finish it.
It is a raglan shaping , and it is long one about 86 cm. I have changed the pattern to be wide from the bottom , and gradually narrow to the shaping armhole stage. The original pattern was straight from the bottom to the armhole shaping as it was a sweater pattern. I am not straight from the bottom to the armhole shaping lol.
Here is another picture to the back of the coat:
