Creating depth in a vector drawing

[angelize]

Here is the first of what I hope to continue as a series of videos. Part narrated Xara presentation and part screen demonstration here is my method for creating the illusion of depth. Any feedback on this will be much appreciated.

I apologize for the coughing in the middle of the video, I fought a tickle in my throat through a good portion of the screen demonstration.

For anyone who is interested the source materials I used in the video can be found in the Clip art gallery.
