Just curious, what criteria do you hold for giving out a 0, 1, 2, 3, 4, or 5?

After having gone through one rating process, and then having filed through the catalog, not even the winners seem to get above a 3 average normally.

I might be a little liberal in my rating.
0 is for proven copies.
1 is for a design that's obviously lacking effort or is just plain miserable.
2 is for a design that looks like the person tried but just didn't have the right stuff to make it happen.
3 is for a design that is good, but doesn't hold any interest for me personally.
4 is for a design that is impressive and piques my interest, but that I wouldn't buy.
5 is for a design I think is really great and often enough wouldn't have thought of myself. I would consider purchasing.
5 and a Buy is for a shirt I would absolutely buy and wear often.
