I started using a wooden texture and a gradient color to give it a bit of depth.
Firstly I used a wooden texture with a gradient overlay
After that I basically put some elements like a building with a woman, a crazy dude with a mask, an little deer on the top of the building.
Started messing around
The next thing that I did was pretty simple, I mirrored the elements, and aligned them in the center of the page.
Same elemets, duplicated and reflected
The image needed more elements, I put a rainbow behind the towers, added some more elements like those balloons over the girl, those tribal elements behind the buildings, everything downloaded and free.
Spice it up a little bit
The abduction laser bean was created and, basically, it's a gradient mesh with the hard light blend effect.
The abduction part 1
To give more the idea of abduction, I put an illustration of myself behind the laser with a motion blur effect, so it looks like Im being abducted.
The abduction part 2
At last but not least I added another illustration in the middle of the page, with some green branches behind it.
The final result, really simple and fun.
