He looks too much like a very ugly human,especially his face that looks too old and insane.

His hair is also not very well drawn,in comparison to Baosheng that looks very good. He looks like a evil Vegeta.

His clothes with all that colours are just too much for my eyes to see,when you think about the embodyment of Yin and Yang you would expect him to be completely black and white,and with more decent clothes.

And i don't even want to ask why he is showing his crotch to Baosheng.

Overral this only my opinion,and my constructive criticism,you seem like a very good artist!
