This looks very good. Only comment would be that our standard of practice when assembling a built-up header is to make the faces of the vertical members (2x6, 2x8, 2x10 etc) flush with each edge of the plate that is nailed to top and bottom. Having the faces flush with each face of the top and bottom plates helps with backing above the window and eliminates the void behind the sheetrock above the windows and doors.
And generally we put 2 vertical members in a built-up header for 2x4 wall, and 3 vertical members for a 2x6 wall. This is not actually needed unless the opening for the header is a wide one (garage headers up to 10', wider windows for example, but is our preferred method so we do it for all built-up headers..
These may be just local preferences, but, wanted to pass this along.
