My calligraphy wording picture doesn't pass the standard

[catglue]

My picture doesn't pass the standard but I don't really understand what is the real issue (as in the attached) only "nice" calligraphy picture is passed. 

Please help me identify the problem. Thank you in advance.

The edges are not smooth. Also, if you submitted these as PNG file type they must be transparent.

When viewed at 100%, the edges start to get messy. You might be using too many points.

Do Stock customers really buy words?  That seems like a strange thing to buy when text is so easy to produce in any graphics app.

Also Stock is a global service.  Only a small percentage of people use English as their primary language.

Besides the quality errors that where pointed out, I also question the use of these assets, as lowly talented people could easily reproduce your assets, and that with any text that the could imagine, enen in all languages that they speak. At the end of the day, even if at a high quality, I doubt that these assets have any commercial appeal.
