a word of fairness
To be fair, I think Wikipedia's kinda understaffed. The fact that they aim to make it free for everyone, and that they rely heavily on the community to write and edit entries, means that they probably do not have the resources available to reject entries in a more humane manner.
I got the implication that Wikipedia causes 90% of aspiring artists to give up their dream, although after reading it a previous review I got that clarified. I'm sure every artist, successful or not, has experienced the kind of heartless impersonal rejection that you mention. I think it kinda acts like a sieve; it separates those who would persist till the end from those who do not have what it takes.
Lastly, if Wikipedia was a site about the many different artforms, like Newgrounds, and they were treating aspiring artists like that, it may be justified in saying that they should know better. However, I believe that it's a site concerned with the free exchange of information, not with developing artistic talent. Hence, I don't think it is reasonable for them to consider the ego of artists, when it really isn't their concern, or even what their site is trying to achieve.
That aside, I liked your work. Just thought I'll say something in defence of Wikipedia.
