My slant on Willem's critique is the scrolls on the left side all flow the same, up or down. Then on the right side you have a scroll on the top and on the bottom that do not follow your flow. For me they draw the eye due to a lack of continuity. This was addressed in a similar situation recently concerning one of Sebastian Leyh's scrolls. Both layouts look good and to the untrained eye there is nothing wrong with either one. The bottom line is "Are YOU pleased with it ?".
