Design a hallowean invitation

We are holding a Halloween party at our home and want an invitation making that we can send out to our friends and family. I have attached a photo of our house. The main design work is to adapt this image to make it look very hallowean themed. I am visualising skeletons in the car, the sky changing to something moody and the house with spiders etc etc. I do not have the best design focussed mind to give an exact brief so will leave it up to your creativity. We would then want a hallowean typeface for the address and decription with some cobwebs etc over the invitation.

Maybe we will do double sided A5 with an image of the house on 1 side and the wording / invitation on the other.
