Upcoming Color Contest

I'm really excited to reveal a new coloring contest that I'm in the process of setting up for you all. A little teaser: it will be an exterior this time.

In organizing this, I wanted to ask for your suggestions.
  • What would be a great prize for the winner(s)? (within reason, of course)
  • And would you prefer for the competition to be judged by me, or would you all like to vote for different categories?
Stay tuned!
