"2D Art" is a blanket term I came up with to describe more traditional styles of work that don't involve Daz or Poser. I'm open to suggestions for a more accurate naming convention, but we do welcome paintings, sketches, drawings, etc.. Just not photo manipulations.
I wouldn't call 4 months a "short' warning, but I understand your concern.
VoD succeeded Art of Darkness in 2016, which was online for 10 years. There are no guarantees in life, but 10 years is my minimum benchmark for PiP. After that, we'll see how everyone feels about continuing.
