Thanks for the comments ;-)
It took me 4 years to learn how to create the models, now I have 12 species, 2 babies and a juvenile, so 15 animals. 3 New animals will be make this year.
I used two methods, the first one was to scan maquettes, making them symetricals, adding details, making a retoplogy, unwrap UV and making textures.
The second one was to make a low poly model in 3DSMax, and adding details and textures on Mudbox or Zbrush.
After I just have to add muscles and making animations. ;-)
I'm making a new demo reel, with this demo reel, I'm making a little book, 3 in French language, 9 in English language.
Each book and demo reel disk has a number and will be sent to some people who inspired me during my 4 years of process.
Here are two pictures of the disk which will come with the 36 pages book, fully illustrated ^,^ :

When the books and disks will be sent, I'll wait a couple of weeks and I'll put my new demo reel on Youtube ;-)
