I can take constructive criticism. I can. However, I feel I am not alone when I say I don't like having my work ripped up one side and down the other by someone who believes he/she is being constructive.
In my job I get to use my creative side a little bit. I am in the middle of making a brochure for our big office meeting in December. I showed the logo mock-ups to my boss and the big boss. The big boss gave me the A-OK. So, now I am making the brochures with approved said logo. Let's keep in mind, these brochures are still in the developmental stage; they are not complete. That's why they're called mock-ups.
I showed a few brochure mock-ups to another person in the office to see which design looked better: a three-fold or a two-fold. Well, the person liked the three-fold (which was all I wanted to know) and then added that the logo isn't up to snuff. Um...excuse me, the big boss has already approved it...I'm not going to redo it because you don't like it. Your vote doesn't matter at this point; the big boss has spoken.
I'm all for things looking nice and professional, which I try to do. If the big boss is happy, all should be happy. Picky, picky, picky!
