Help me please

Hi, I'm writing this essay, but I'm not sure about this paragraph, does the text has grammatical mistakes?:
"Among other similarities with the portraits of Buddha are the depictions of children clambering over John Yu's head and shoulders, and the serene expression on the Doctor's face. On one hand, the children that can also be found on portraits of the “laughing Buddha” represent, according to the Chinese tradition, prosperity. By the other, the serene expression on Doctor’s face can be associated with some of the portraits of Buddha meditating"
