Hmm.. well i did read something about making different objects your primary focus in pictures, almost like you force the viewer to look at what you want them to look at in the shot you take.
For example, your first picture, although it is not centered around the object (your car) it still draws the attentione, but if you would have moved the camera a bit to the left, the attention (i belive) would have been at those awesome looking snowcovered trees.
And even though the copcar isent centered, it's still the primary objective in the picture.
Damn i gotta work some more on my shots.. good stuff Kracus.
Now i wil leave you with some more (retarded) levitation pictures.
nananan.. SPIDERMAN!!!
*Edit
Oh btw, i forgot to mention.. all you that can not afford a real tilt-shift objective (like me), there is this awesome website that lets you create tilt-shift photos with different (easy) tools and save it on your hdd. Beats photoshop if you ask me.
Here is a tilt-shift i took earlier today
