You should have placed Rom's transformation on the right and Ram's transformation on the left. The way they swing their wands at the end is in the shape of half a heart.
I knew that some skills get different why you use them in HDD, but I never knew Nepgears def-buff was one of them... EDIT - You also missed an oppotunity by not having Rom and Ram in the opposite order during their transformation...
it is annoying that rom has 8 heal/supportive skills while ram has only 2 of those and compile heart/idea factory not fixes that during all the neptunia games it released.
