I hope this question doesn't fall into the:

"... Because I clearly need them ya' Big Dummy!!! (Ala Fred Sanford)" category.

But, in reference to you latest page, specifically vanishing points;

I always though vanishing points were used to determine static objects with straight(ish) lines (walls/buildings/cars/etc) with established lines, yet you used them in these panels without any of these (I'm sure you used them before and I just didn't notice).

Do you always use vanishing points in your work to determine angles no mater what the environment?  

 

Beyond the white boarder, I believe that the effect is being achieved because of the reused background is a tiny bit "fuzzy"... the figures are crisper and have more contrast... helps give it that depth of field.
