Here is the final result:
NOTE : If you request a tutorial, be sure you want a more detailed one, not a simple layout like this.



Start with a new document. Size should be 760x770 pixels

Now go to Photo-Shop-Brush.com and download the following set of cloud brushes

Then create a new layer, and with brush tool, make some simple clouds on your canvas



After that place a image with a car



If you have Talk-Mania Big-Pack
Load a set of tribal brushes. In this pack you have over 4000 different brushes in 3 sizes. I am sure you will find a nice brush.
I have created a new layer ( press CTRL+SHIFT+ALT+N ) , then with Brush Tool , create a simple drawing



Over this blue shape, place some images with your main products



Now it is time to use another 2 brushes from Talk-Mania Big-Pack
I will use the first one to create a simple logo.
Remember to create a new layer , then with brush tool, create a simple shape



The second brush i will use on the bottom of the layout, of course on a new layer



Then duplicate this layer. to duplicate a layer, first be sure you have the layer selected, and press CTRL+J
This shortcut will create you a new layer above the initial one
With the clone layer selected, go to Edit > transform > Flip Horizontal

Then with Move tool place the second layer like me



After that with type tool, add some text. This is my final result. Because this one is a very simple tutorial, tomorrow i will create you a more detailed tutorial
