Yours is not cut evenly on all sides. Look at the space between the edge of the card and the dotted line on the bottom. The space widens from one side to the other. This gives it the same look as a miscut card. If you think of it as a 7 with a qualifier, it would be quite accurate. Most people who submit these and get high grades are machine cutting them. I agree with you, having a little white around the outside is more eye appealing, however, I think it's easier to get a straight cut (and helps the grader out) when it's cut just along the line like the example in the link you provide.
