I think that the WIP pictures are looking beautiful and I was curious what modelling software you are using for the game.
Everyone uses either 3ds max or Maya to construct our models as well as animate. We also use a wealth of other tools to assist in the construction phase. Todays technology truly does make the process more streamlined and easiser to deal with.
3D modelers are used in a wide variety of industries. Many 3D modelers are used for general-purpose that is used to produce models of various real-world entities from plants to automobiles to people. 3D Studio MAX is the nice option to learn 3D modelling. It can be extended and customized through its SDK or scripting using a Maxscript.
