This almost entirely a response to VidGameDude.
I don't think the "zbrush makes it too easy" argument is valid at a criticism. As stated, it sounds like your fundamental point of view is "Don't use new technology because it hamstrings your artistry." Meanwhile, 3D art in general is a manifestation of that. A "true" artist knows enough about perspective and perspective distortion that they don't need a computer to calculate light refraction off of polygons for them. This image could theoretically have been made by hand, or even in MS Paint; do we denigrate the entire 3D Art genre because it can be done using other media by "more skilled" artists?
And even within the world of 3D Art tools, I have literally spent *months* trying to make a human face in Blender, and it still looks like a partially melted ugly doll. Blender is pretty fantastic for particle effects, though, and for using simple algorithms on simple shapes to make complex patterns. So I might use Blender for a starship, zbrush for its pilot, and GIMP for post-processing: so what? Certain tools are best suited for certain tasks, like in a kitchen. So if sculpting organics is like chopping vegetables, then Blender is a like carving knife and zbrush is like a ... blender.
