Half-faced Aliens Costume

My husband and I decided to dress up as some kind of scary blood sucking aliens. I used fake nails for the teeth and liquid latex to attach them to our face. Painted with blood paste. The bloody flesh was created from cotton balls and tissue with liquid latex, when it dried I cut open and painted so it looks like skin coming off the face. We used yellow/red contact lenses in our left eye and black lenses in our right eye. The blue skin make up is oil based and settled with setting powder, so it stayed on all night. The make up took about 40 minutes each.
