I created the Priest character by modifying the Fuzzyman character DexX made for me. Jamalia and Lenny come from similar bouts of Photoshopping (and arm from one character, the eye of another, etc).
The point is that I used DexX's art as a starting point to create something very different and useful for the site. The Priest offers lots of comic possibilities, and at the time I created Jamalia and Lenny there were few other black characters on the site.
I offered them up with the caveat that DexX had veto ability if he didn't like what I did. Thankfully he felt that I changed them enough to make them worthwhile.
What is the point of a Neovid with short hair? My constructive criticism is this: Figure out if there is a character that would be useful and unique, and if you modify an existing character to create it, I for one would not mind if you used parts of existing chracters if the end result was sufficiently different. Of course you'd have to get an okay in the end from the original artists, so it's a gamble if you create something and they don't like it.
For example, one thing we're missing is... the Pope. Or a character that could be generically the Pope or a Bishop.
