I really like #28. It reminds my of a stylized Ganesha. Can you google Ganesha, a Hindu god, to see if you can refine it? I think the font is a bit too blocky. Can you soften it, and perhaps try writing it with an Indian flair such as

Entry #27 reminds me of a stylized deepam or light. I like this as well, but do you think you can look up a deepam (I just googled it, and found lots of pics) to inspire the next iteration of this image. There is something very special about #28 and #27 as they give a nod to a rich heritage out of which yoga came to be.
