Yep, here it is. Page 20, just like I promised :)

You see that cool picture of that house? The one with the sun rays? Yeah … I made that in 3D. A neat little program named SketchUp helped me out there. It’s free you know …
So, can you call it “cheating”, when you use programs to help you do stuff you can really do by hand? … Hell No.

I chose to use 3D to:
1. Save time.
2. Get the perspective right and
3. Be able to choose a camera-angle that would fit the purpose, without having to redraw again and again until I finally get it right.

You think THAT’S bad? How about if I told you I used 3D for the lower left panel as well? Uh Huh!? Yeah!

The bottom line is, if it will help you make a better product, or you just want to save time or whatever, use whatever means necessary and do it! … Just don’t be stupid and tell everyone about it afterwards (like I just did) … Hah! Naaah, I’m just kidding :p

Anywho, it’s getting late and I’M going to bed now, sooo I’ll see you! お休み！(That’s Japanese and it says ‘Oyasumi’).
