Ok...
You thought about it & you come up with this composition.
I know what you try to impress with this comparison if i got this right (that the phone is sooo old that belongs to the Jurassic age).

Nice idea but the whole composition doesn't help a lot (IMHO).

Yes karaflazz, I meant to show the "natural" habitat of a dinosaur-mobile among his fellows in a shadowy vegetation.
The problem is I could not find any living dinosaur this morning so I had to use a book...

What you don't have dinosaurs in your area?!?! Seriously though, if you want to go with this idea find a toy dinosaur, the 3d aspect will help convey your idea better.
