When you are done with shaping just hit -Q- key selecting the whole area, but without the character itself, so you will have to Select Inverse.

...and hit delete deleting all the character area. Note that you should stay on the base layer (Layer 2).

Now, about the design. Just make several copies of the layer (I've merged all my effects into one).

Make one smaller than the original and one bigger then the original.

I
 
will now transform each of my newly created layers and put them into perspective.

I will not explain what perspective is because it will take a lit of time to you to understand and feel it. Just try to feel it, feel when the object stays right, on the right angle, just like happens in the real world.

I will lower the opacity of each layer a little bit.

And we are done here! Enjoy the design!
