#21 with a heart as you requested. I've also changed up the font and arrangement.
#22, lots of meaning here. Since you said you like the yin yang, I created a yin yang shape from two leaves. The negative space inside the leaves is heart-shaped, and the two together (heart + leaf) symbolize healthy eating. In addition, the yin yang creates an S shape for "Soulistic".
