There was an app for free on iTunes called Adobe Ideas for the iPhone (now cost £2.99 for the app nowadays) which I've done some drawings perviously I've done on my iPod Touch.

I was Influenced by the image of the Ferrari 250 GTO to created it in Adobe Ideas.

I started with the image behind as a template, draw in the basic colours onto another layer.
Then I remove/hide the real image reappear as a reference on in a while. Then add more colour to the main image.
Then re-tidy the details/adding and removing colour of the car with a bit of trail and error. Some didn't work. But, is developing the piece.
Add some details to the bonnet.
Add some more detail, add/replace colour.
Add the Ferrari logo on the side of the car.
Then retouch the front end of he car again for the finish piece of the 250 GTO.
Then I done this with the Ferrari 288 GTO.
And the Ferrari 599 GTO too.
So I take all three GTO cars into Photoshop for a little altering on angles of the cars. Saved as as a jpg file. So here is the finish product of Ferrari GTOs' below.

That is all. Bye.
