Maximum score: 15 points

In this task we propose you to create your own model.The topic is very broad which allows you to demonstrate your folding and

You can choose any subject you wantif it matches the topic. It can be just starships, astronauts or planet

The model can be created in any style, technique and complexity level.But there still are a few basic rules:

- one convex polygon sheet of paper (e.g. square, rectangle, triangle,pentagon, hexagon, etc.);

- any color, size, type of paper, etc.

- you can use MC+paper, foil-paper, wet-folding as well;

- no cuts, no glue;

- no painting or varnishing of the finished model (you still can paint thepaper before you start folding);

- minimal editing of the pictures is allowed as long as it doesn't affectthe appearance of the model. E.g. you can crop photos, reduce the noise,change color balance but you must not add, erase or change any details;

- you can make a composition photo with as many different models asyou like, but only one of them will be judged (you must specify whichone is it);

- you must include CP or other information about your model (so jury can see that the rules are observed).
