A toy train I modelled and rendered in Cycles at about 600 passes. I pretty much copied this model, http://cgcookie.com/max/2012/08/23/tiny-train-toy/ but instead I made it in Blender. If you want to read more about it you can go here, http://davidzerba.wordpress.com/2013/01/19/toy-train
I provided the texture and the HDR in the zipped folder.
Incredible!! It does look exaclty like the model in the tutorial except in Blender!! Very nice work on this, we appreciate you sharing it with the community. :D
This looks very real good job :)
