All of the following are characteristics of the strasbourg style except:
emphasis on emotion
draping effect of stone clothing
emphasis on dramatic gestures
emphasis on heavenly beings

I think that the answer is EMPHASIS ON HEAVENLY BEINGS.

Strasbourg style has the following characteristics:
1) emphasis on emotions
2) draping effect of stone clothing
3) emphasis on dramatic gestures.

I based my answer on what I read about the Strasbourg cathedral. Its art and sculptures revolve around Mama Mary, the Prophets, the 12 Apostles, and people depicted in the Bible. There is no presence of angels or any other heavenly beings.
