If you are working with literally anyone else, or if you submit your work anywhere, you are almost certain to receive (hopefully good) critiques of your work. There are a few things to keep in mind when reading them and revising your work. 

1. You are under no obligation to take action on any of the critiques. You may think that the people offering you the critiques got everything wrong.  You may think they missed obvious things.  You may decide that their aesthetic suggestions do not fit your ideals. Guess what?  That is ok. You are the person making the design, and you get to make the final design choices.$^\dagger$ So, please don’t feel the need to be defensive about the critiques.  They are not commands, they are someone’s thoughts. They are worth considering, but do not require action.
2. The critiques reflect the thoughts of another human. This is critical to realize. It is all too easy to dismiss critiques.  It is easy to tell yourself “Oh this person just wasn’t paying attention enough.” But the fact of the matter is this: the critique came from a human and you are going to be trying to communicate with other humans. So, it is always worth seriously considering the critiques you have. If a few people are confused by your design, it is very probable that other people will be as well.  So, take these critiques seriously and do give them due consideration when working on refining your designs. 

A critique is not an argument #

Similar to what was stated in how to give critiques, the goal is not to “win.” The simple fact of the matter is this: the critique you receive is from the past. It expresses an opinion that already happened. You cannot go back in time and change it. Thus, the most productive response to a critique is this: be grateful for the time the critique spent on your piece, decide if you want to implement their suggestions, ignore them, or ask for clarifications. Again, you want clarifications, not an argument.$^\ddagger$

$^\dagger$ This is different from when you have a boss that tells you what you have to do. However, in that case, you are not really receiving a critique, but being delegated to.

$^\ddagger$ I am also aware that there are ill-willed critiques… responses offered by the equivalent of internet trolls. My advice is the same that people give out on internet forums: do not feed the trolls. There are, in my opinion, two correct responses to critiques you do not agree with: you can either thank them for their time, or you can say nothing.
