I have the original render of the house which is very plain.
After awhile in photoshop and adding the sketch filter this is the end result
This is homer's car. If it resembles a chevelle a little well you would be right. I couldn't really find any good blueprints or shots of the car, I decided well it almost looks like a chevelle. I started to remove the parts that made it look like a chevelle and started modeling out the areas that needed to fit the car's look. Think I did a pretty good job. Once again I have the original render along with the photoshop pic.
