This was done for EF21 Me and had a room together, and I wished for a doorhanger. The downside was that I've decided about that the day before departure D:

I haven't picked up tempera since the end of elementary school. It was a blast, tho I don't know almost any tricks and techniques, I think it got off pretty well.
Circular door hanger? NEVER AGAIN. I had to crop the base because the laminator wasn't big enough and also we didn't have a big enough paper thing.
And I showed this to and she was like "Duuuuuude! You don't just paint the tree trunks with brown, they are grey-ish!!" So here's a lesson learned. x3
I also haven't included almost any shadows, because I don't know how to.

Took about 4 hours with the help of a hairdryer. Without it it would probably take about 2 days. Gauche technique

If anyone is interested I'd love to do something similar. The only downside is that I can/don't know how to send the physical copy without being destroyed by my country's postal service. I might try tho, without any guarantees.
