Your models are good, but I think that your models are very,very cheep.Only you loose from this.
The Lion - 65 $..?So many work - and in the end Nothing.
If you want to make animals with fur,..first teach the hair and fur modifier.The LIon's fur is not good.
And forget the Scanline for render,.. use only Vray.
Anyway the modeling is good, as someone says - you have good starting point.And again the prices.....!
