I did this composite using 3 main elements. The car using a loaned VW toy from a local antique shop, the background oasis from a desktop wallpaper picture found through Google and the girl I found using Google and asking for flower child pictures. Google brought up a costume retail shop with this low-res outfit that was for sale.

Shot the car outside at around 3:00 PM full sunlight using f/8. Back tire is not in focus should have shot at least f/11 for more depth of field.

Started out with the background as my base and made no adjustments. Next layer was the VW made a mask using the pen tool in Photoshop. I am starting to master this tool that is so hard to get use. Once I found all the keystrokes I found it better that anything else for sharp clean masks.

Next layer was the girl. Made a mask for her and reopened in Camera raw and use luminosity and sharpen to reduce some of the bitmapping. Put her all over the place till I found this spot that looked the most natural. Added shadow layer for the car and the girl. Used Gaussian blur and Gradient tool to soften the shadows. The daises we a bit flat and used selected color to enhance color. The one on the left hood was washed out so I duplicated the right one and put it on the left then used selective color layer to change it a bit.

I will go over any of these steps with more detail if asked but for now just wanted to help others try and make something out of a lone not so interesting shot.
Let me know if this was interesting or a waste of time giving the details or posting composites.

...and a little bit of history as well as some photos. Wells is a medieval city nestling on the southern side of the Mendip Hills with the mystic Somerset Levels stretching away to the south and west. The history of Wells goes right back to Roman times when we know that there was a settlement, probably because of the springs that bubble up here. Wells gets its name from these springs which can today be found in the gardens of the Bishop's Palace.
Wells is the smallest city in England with about 12,000 inhabitants. It can call itself a city because of the famous 13th century Cathedral. It remains remarkably unspoilt and has many other historic buildings including the moated Bishop's Palace, Vicars' Close, St Cuthbert's Church and a good local museum. The Wells Market Place, with lively markets twice a week, the narrow streets and an eclectic mix of building styles all reflect on the continuing development of the town throughout the ages.Please check out the download on the cathedral to see all the statues.
