I recently attended a local LUG meeting which featured a MOC competition with the theme "Animals". I took that theme in a mythical direction!
I didn't win a prize, but got some great comments. I used a lot of small plates, bricks and slopes, aiming for an asymmetrical look. I wanted the appearance of something ancient, and partly eroded. Note the two different headlight bricks used to make the face uneven.
It's also now a LEGO Ideas project. If it gets 10,000 votes, it will enter a stage of official review by designers at LEGO and has the chance to become an official set.
