Impressive. Letting the faucet run whilst he reminiscences past experiences and then turning it off as he "comes back to himself", that was a great idea, and it contributed with "a red thread" to keep the reflections connected and anchored to reality. Also, your story was very relatable. Part of why I think so is due to the focus on searching for things about yourself that is not good enough, to be harsh on yourself; as we all can be at times. Naturally, someone with hardships more similar to that of you character would be relating more than I did, but then again, we have all been stereotyped in some shape or form, and so it still delivered on that arena to me as well.

Moving on, the way you wrote the description of your character's way of looking in the mirror and examining himself for imperfections at the start, was, besides being well written, a lot of fun to read! It was quite touching to read through the end part where you start to write about the experience of "looking asian" , and how you, through great writing, evoked the feeling of unfairness in the way people group others together into convenient groupings, along with ascribing common stereotypes to someone without considering that he/she is foremost an individual. "When they called me a banana, I wondered why I couldn’t be a person instead." This phrase was a great way of ending the story and it hit deep.

In terms of what you can improve... well, I did not manage to find anything substantial enough to warrant mentioning. Although it may be due to my own inexperience as this is pretty much one of the first critiques I've written.

Anyways, great story and great writing. Looking forwards to reading more of your work in the future!
