To be honest with you, there could be 2 things.
1. The admins are all anoying you and just because they feel so, they are not going to authorize your skin. it has nothing to do with quality, they just want to **** you off.
2. The admins happen to have bumped into some real live situations and with dozens of uploads a day they just cant keep up with the flow. It can take up to 5 days until your theme gets trough... if it is already 5 days ago, read option 1.
