Frustrated...

I have to say, I'm feeling a little frustrated right now. I'm not sure how this happened, but for some reason no one in my peer review group did peer reviews! I took the time to review all of theirs but didn't have the favor returned. This was frustrating to me because I didn't get any sufficient feedback. I wasn't really sure if there was anything I needed to fix. Judging by my own standard, the work I've done looks good-to-go, but someone may have had a different opinion; I'll never know. I don't always trust my own eyes because I don't know everything and since its my own work, its easy for me to miss mistakes. It's important to get second opinions in order for my work to be at its best. I hope this isn't going to affect my grade.
