Constructive criticism shouldn't be taken negatively, as it comes from a place of someone with a different perspective and/or set of skills caring about what your content and message is. When someone takes the time to interact and to offer feedback, it's a way to see how what we've created or what message we're sending out is being received. How could we make improvements and continue on learning more without this feedback?
Thanks for your video and I wish you the best of luck and success with your upcoming interviews!
