I can see how this is a good thing, however, I'll suggest (and it's a question/suggestion, that's all) that there are some (like me) that largely do the team comps.
That doesn't mean that some stuff isn't mine alone.
For example, the art that jdmdisney99 suggested was mine. I had feedback, of course, but I did all the work.
Red gets feedback, but that shouldn't mean her art isn't acceptable either.
Team Air's Middle Earth was mostly me as well. ctxak barely came in. Just ask any judge on the PM thread, it was silent (even though I was sharing).
I hear your point, however, perhaps it's best to let people nominate first, then clarify. No reason why a group can't win.
If we want to separate it out, it's simple, trim down the categories, then make a "group/indy" nomination for them.
My 2 cents.
