Actually, this is the first concept of the T-Rex...

He went out for a walk and the rain began to fall for good. He forgot his umbrella and all the taxis were running away from him, so he got a little pissed off...

This one shot is part of a larger project.
Thank you all - great dudes that made this possible.

There is also a short process showing how this shot was made.

And what happened to the T-Rex, you may ask ...
People say the T-Rex is still walking somewhere in the rain.
