This is a model of a peacock. Peacocks are known for their colourful tailfeathers, which they use to impress females. This model has 1750 parts and is as colourful as the real bird.
I was initially inspired to make this model for the "patronus" challenge a while back. I made a patronus of a peacock. Because it looked quite good, I decided to also make a regular version. That became this model.
I think this would make a great set, because the colours and the general aesthetics make for a great display piece. I hope you will support this idea and bring it to 10000 votes, so it can become a real set.
