Here is a portrait that I made last week. I wanted to add a realistic human sculpt to my portfolio, and I wanted it to be someone who is easily recognizable. So I went with Patrick Stewart.
I used Modo for the base mesh and the rendering and zBrush for all of the sculpting and fine details.
I'll probably add color, shading and eyebrows at some point, but I have other projects that require my attention now. So it will probably stay like this for a while.
FYI, this is my first post. So please let me know if there is anything I can do to improve the thread, i.e. more info or more renders, etc. I welcome any feedback and/or construction criticism.

Thanks!
