[QUOTE=PLing;20736461]The angle needs to be from top so it looks like you're looking at a miniature. Right now your 2 lower ones look like you're on the ground level and it just doesn't work.[/QUOTE]
It can still work from a lower angle (haven't you ever knelt down at the side of a model?), essentially all you're doing is making a very very shallow depth of field and punching out the colours a bit; you'd just have to be more precise in masking or make a depth map for the lens blur effect
Did it work?

I tried in gimp..
I'm gonna make this in the upcoming week.

That's not how focus works

Another experiment:

I spent way too much time on making a depthmap for this. A simple horizontal gradient doesn't really look good in most cases in my opinion.
Did this with GIMP and the focus blur plugin.
The photo itself isn't really good though, i did this just to test the technique.

Why are their bodies in focus, but their heads aren't? Also why is the background of the houses on the right in focus too? Can you understand why it looks silly?
Tilt shift is not just a blurred bar at the top and bottom of a picture.
It's because I didn't make a good selection when cutting the heads out of the blur

what do you mean
New one I just finished :D

Look at a object near you, do you see something really far randomly in focus behind it? No.
All of my attempts were miserable failures :(
[QUOTE=Reg;20758138]It's because I didn't make a good selection when cutting the heads out of the blur[/QUOTE]
And what about the buildings behind? Have you ever used a camera that has a focus feature?
Or even played with the DoF in garrysmod or some sort of game?

[tab]The flower on the left is in focus, that's why the flower on the right is blurred.[/tab][img_thumb]http://www.ryanlawlerphotography.com/images/large/IMG_4616bw.jpg[/img_thumb]
[tab]Opposite way round, the flower on the right is in focus, and the flowers behind it aren't, which is why they are blurred.[/tab][img_thumb]http://www.ryanlawlerphotography.com/images/large/IMG_4636bw.jpg[/img_thumb]
Take a look at some macro photography for a better understanding;
[tab]The focus point is in the centre, the beans on the bottom are closer to the camera than the focus point, therefore blurred, the ones at top are further, therefore blurred.[/tab][img_thumb]http://wvs.topleftpixel.com/photos/bagel_macro_01.jpg[/img_thumb]

OK, let's put this into perspective [hur hur]
focus is based on distance, not position in the picture. Depending on how far away something is, it will be more/less in focus. For instance-
[img]http://www.matja.com/zdepthtutorial/zdepth001.jpg[/img]
let's say that the brightest white object represents the most in-focus, and the ones farther back are not in focus, and get blurrier (or darker in this case)
now, in a scene with vertical objects, like people, trees, poles or whatever, the focus will be pretty much even on the whole object. A person's head is just as far away from the camera as their feet (unless it's a really odd angle picture), so they'll be the same focus.

the point of tiltshift photography is to force this perspective to be extreme, and the short [i]depth of field[/i] makes the image look like it's tiny.
given the principals I just explained, the focus in your picture-

should look more like the focus in this picture-

because the town in the distance is so much farther away, it's completely blurred out, whilst the people and the mountain are much more visible.

I tried doing it with Portal.

It sucks.
