:unsure: :)

Duplicate the car and set it on overlay. Then go to filter>gaussian blur. The quality will be much better. I also recommend putting a shadow under the car. Right now it looks like it's floating on air.

Also, try to cut out the car better. Personally, I use the polygonal lasso tool.

I used the Extraction Tool and erased some of the left over background...

Update, i did what break said.

Not a shadow like that. Make a new layer under the car and start brushing with a soft edged brush under it to make it look like a real shadow.

I see what you're trying to do, but its not working. The background its self is very filter-looking and the border is non existant, or thick and noobish. A good render, and apossibly good idea, but you're new, so it was poorly executed. There are a few car tutorials out there, check em out
