I submitted my art piece at least 2-3 days ago, but it's still in the pending approval state. I've seen other pieces passing through, so I thought it was just a matter of time, but today I decided to look for support and I found the thread about approval criteria, so I'm asking: is my piece still pending because you don't know if you want to reject it or not and you're waiting to define some general rules before approving it? 
Or should I just wait since everyone's busy and probably I should have never submitted this post?

Best regards

Lol shutup souly.

I'm afraid yes, things will take some time if the piece is wavering from approval and disapproval. Some of us are busy, others feel they need a second opinion. I must admit your piece is definetely not as bad as most others, but there probably still could be more done with it. I'll talk it over with the other guys and see what they think. As i always say... while you wait, PIXEL!
