Maybe the reason you haven't had any responses is that you're simply asking for too much? I get that you want to interest the avatarists, but you're asking for two characters in the same avatar..... And that was a simplification from something to do with a dragon?
Plus if your post isn't on the newest pages on the thread then i doubt any avatarists would find it without backtracking a LOT.
Maybe you should try a less complicated request at peak times more recently, instead of getting angry about an unanswered post which is practically invisible by now....
Just a suggestion
Also, one last thought... if the request you have is too difficult for you to attempt, then it probably will be for the avatarists too
