Hmmm, I can see your problem...
You blurred wrong in the first one, you used a motion blur while you need to do this:
Select a radial blur and set the mode to "zoom", the only now is for you to try and find the zoom point, Dman has a usefull tutorial on it in his gallery, I recommend you to take a look 👍
In the second one, I can see pieces of the car being blurred, so that must be the fact that you didn't played around with the layers, do it like this:
Take the polygon lasso tool and select the car, after you've done this, feather it to an amount of "2" (right-click, feather). After you've done this, right-click again and click "layer via copy", the car will now be put on its own layer without the background.
Afterwards, click on the background and duplicate the layer twice so that you have four layers:
- Car layer (always on top!)
- Background copy 1 or 2
- Background copy 1 or 2
- Background layer
You do not touch the background layer and car layer for blurring, only the copies. You add a blur to the copy on top of the other copy, while you add a gaussian blur on the other one, like this:
- Car layer
- Background copy with blur
- Background copy with gaussian blur
- Background layer
Some people say you need more then 1 layer with a gaussian blur, but I never do that, it's only necessary if you cut out the car badly, give it a try 👍
The colors in the two shots are very good BTW 👍
