Please be aware the criticism is part of the craft, just as praises and awards are. If you can't take criticism, don't
Also please be informed that when you ask somebody to review your work, that means that they can point out your weaknesses as well as strengths, and to not be angry at them for pointing the said flaws. It's one thing to receive unwarranted criticism, it's another to ask someone else to look at your work, and be mad at them for giving an honest--if unflattering--opinion. Readers are not yes-men nor are they idiots, even if they are your "friends".
