My word: Zing
The google definition is energy, enthusiasm, or liveliness. But according to the answers of others that I asked on the meaning of Zing, it is a fancy word for magic and wonder.
Model 1:
Model 2:
In Model 1 and 2, I was still unsure as to how to translate the meaning of Zing into an arrangement of rectilinear volumes. Thus, only trying out arrangements that defined the dominant, sub-dominant and sub-ordinate.
ThanX for spearheading the posting of your 3D Sketch Models Ying Hui 🙂  Both of the models are fairly good first attempts at distinguishing D, SD & SO.. 🙂 (although the SO in Model 1 could be slightly smaller)  However I do not quite sense ” Zing ”  in either composition. What is your definition of Zing?  Do try other configurations of expressing the word for next session.
Do attempt some 2D Sketch Analysis of these 2 Sketch Models to see how else you can improve on them.
