Scarecrow

Due to my ever populating pest problem i have constructed a scarecrow. As i am frightened of scarecrows after watching one to many horror films with them in e.g. Wizard of Oz. So i have made one with a friendly familiar face, incase you didn't recognize the character i have based my scarecrow on i have it to look like Harry Potter. The head is made out of papier masche so how long it will last outside i don't know.
