The idea of the Challenge Me is meant for Artists with Art Block, or are just plain bored! Other users challenge the Artists to do things like-

Redo old pictures (Pick an old picture from their gallery)
Draw with Mouse or Tablet (I use a tablet)
Draw without Smoothing or Pen Pressure
Draw an animated character
Draw a many subject picture (a picture with many characters in it)
Do a species sketch
Draw in a certain style
Combine two or more animals into one
ETC.

You can pick from this list or come up with something yourself. Feel free to leave a challenge post!
