Here are my three sketch models that has a dominant, sub dominant and subordinate in one composition. Below are my 2D sketch analysis for each models on how to further improve them!
With this composition it is noted that I needed to make the dominant volume more prominent while making the subordinate thinner so as to not confuse and make it seem as if there is two subordinate. Wedging the subordinate and subdominant at 1/3 the length helped to give the composition almost a a float like effect.
With this composition, it is noted that piercing the subordinate through the subdominant makes it interesting but it is also hard to balance the composition between the dominance of the length of the subordinate and the dominant. Again, my dominant needs to be more prominent and I also decided to thin down 1/3 the subordinate to make it more obvious.
With this composition, wedging the subordinate and the subdominant at a corner makes it interesting. However the dominant needs to be more prominent and maybe even cutting the subordinate shorter and shifting it not too in the dominant will make it more obvious as the subordinate.
