That is completely normal. Drawing involves a lot of thinking, and it can really be quite overwhelming - especially when I'm outlining all of these things you need to work on. Getting stressed and having it cause you to forget important points is entirely normal.
What may help is to read through the critique (while looking at your drawing and trying to identify what I'm talking about on your drawing), then taking a break. Come back to it later - like perhaps the next day - and try doing the same thing again. Then you can try doing another drawing, and compare it to the critique you'd received, see what you'd actually ended up improving upon, and what may have been forgotten. You may then wish to give it another shot the following day, if many elements were missed.
