^its not a story dude, its to help the person who made a graphic to improve in his skills.
As several opinions will help him to improve.
For example, you made this hbk sig..
now each person has his own inspection eye that will pick the flaws and also will give you some ideas, that you can use for another one you will do later.
Thats the purpose of the GFX Showroom, its not a place just to let others see how good you are in gfxing, but its actually to let you know how others think about your work, not by a rate, there should be a reason for why you gave a high score or a low score to it.
