Example of 3d character design: Ent.
Obviously this character concept was inspired by the Lord of the Rings, but I didn't want to simply reproduce one of the movie characters but create a new one instead that would look as it belongs to the same universe.
I started the process of character development in a traditional way with silhouette thumbnails in Photoshop to which I subsequently added minimum color to get simple thumbnail sketches.
Of course most of the work for this character concepting process was digital sculpting in ZBrush. After finishing high-poly character modeling process, I tried ZRemesher and 3D-Coat's auto-retopology to optimize the mesh, but not satisfied with the results I ended up doing the retopology manually in Maya, at which point I also done the UVs. For texturing I used a combination of Photoshop and the robust texture painting capabilities of Mudbox. Final clean up was done in 3ds Max where I also added some details like small branches and leaves. I used VRay to render the final images.
This project served as a sort of workflow research where I experimented with capabilities of various software to find the combination that best works for me.
