Rabbeted Oblique Scarf Joint - 'Okkake Daisen Tsugi'

My first time trying this rabbeted oblique scarf joint or 'okkake daisen tsugi'. I used this joint to join two pieces of 4 meter long pine. The dimension of the wood is 4"x4". This is later to be used as one out of two members holding the roof in a timber frame shed. Tell me what you think and thanks for watching!
