If you are not going to put sashing between the blocks, I would "basket-weave" them so that there would be less bulk in some of the seams.
I think you should be consistent in whatever you decide to do. My OCD self would want to "fix" whatever was not following "the pattern".
Interesting question.
I drew three options:
1) The blocks are all turned the same way in each column, but the blocks are turned the other way in the next column.
2) The blocks are alternated both across and down - basket-woven
3) The blocks are all facing the same direction
With the dark gray you are using for the frames/borders, most people probably would not notice one way or another. (I probably would, if I looked at it long enough.)
