Digital Sculpting - Developing my Silhouettes

Out of the 40 odd silhouettes I created using Weave Silk, I have chosen two that I want to develop into Value Studies for ideas. I did one in Photoshop by going over the basic forms I could see in my silhouette and then adding vague details over the top of that, and in light of our workshop today I have created another using ZBrush by creating a base model and adaptive skin using ZSpheres.

The above Value Study was put together using this silhouette. Personally I don't like the general proportions of the character, of the way that I have constructed the characters mechanoid legs.

The above Value Study was put together using this Silhouette, and this is by far my favourite and the one I will be continuing on to use as a base for my final model. While I have been creating this ZSphere model, I have decided that it would be easier to construct this model by creating it in a number of stages. With this in mind, the ZSphere model above will become the base for the Biosuit of my character, the character himself, the crystal core, the wings and the weapons will all be constructed separately and then Dynameshed together to create one single, high poly mesh of my character. The next stage of things I have to do is work out all of the components for the character and then begin modelling them one by one, ready to be combined.

Why do I always have to pick the ambitious projects?
