Well the word; 'forward' is tricky. When we go 'forward' along an incline there is both a pure horizontal and pure vertical element involved with the displacement. So when a steep OP is advanced, we go horizontally forward AND vertically downward. Any unwanted vertical displacement is seen at the nose base and/or below. I guess you could say that it's seen at the 'border' of the midface and the lower face relative to the division of 1/3rds which might kick up perception of changes to midface.

Anyway, the original poster does not have a long midface. So, there's not much point in discussing ways to reduce it.

Right. By ‘forward’ I meant horizontal, but is better described as ‘advancement along the OP incline (decline)’ which will have pure horizontal and pure vertical component vectors.  The ‘vertical vector’ magnitude is smaller per unit of advancement when the OP angle is smaller, which Kadath has the good fortune of possessing.

Yes and good catch on the 'decline'. Yes, like VECTOR components where a vector has a direction and magnitude and we break down the components. (I hesitated to bring in vectors on this board.)
