Thanks unit23,
Nice to hear that you will starting this. Are you beginning yet with 3d modeling and you have 24 hours a day and 7 days a week and so on time, youll get the models shown on your pictures in ca 2-3 years to get the point so.
I dont will give you any tasks, but from my own experince and others this is so.
With hard traing to the ground. I do it since 2005 in 3dsmax with some breakings.
3D on high quality are a learning process over many years. Maybe you can learn it faster in modo with good tutorials there will be time savers.
I hope my models will fits your needs in an later stage, let yourself be surprised what there still is.
The Terminator like hardsuited on the last picture will looks like one of my hardsuited soldiers in early stage.
