A nice gift

Hello everyone!
I did this image in a week of work.
I've used the awesome CGCookie Flexrig for the characters, the Scenecity add-on from Arnaud Couturier for the background city and the Grass Essentials add-on from Andrew Price for the grass.
Then I've used these models from Blendswap (thanks a lot guys!):

"A rose" from <strong>jgilhutton</strong>
"MeanTrikes-WhitewashNo1" from <strong>rianvermeulen</strong>
"Skateboard" from <strong>elmaterdor</strong>
"Tree again!" from <strong>mherpin</strong>

All rendered in Cycles, 2500 samples. The render took me almost an hour using an Intel I7 with 12 threads.
I hope you like it. Feedback are welcome of course.
Cheers,
Nicolas.
