This is the "hero" version of my personal logo with which I started the 3D work.
After working in both Sculptris and Cinema4D, I created a bas relief of my 'hero' logo appearing to be set into the wall of a building.
This is the original large render output from Cinema4D.
A look into the ongoing aging and effects applied in Photoshop, including dirt, grit, stains, the shadows of leaves, and more.
Ivy leaves were added, pulled and altered from a hi-resolution stock image.
The original finished product. 
After much internal debate I'm adding some flourish work to fill in the negative space to make this more akin to the style that is found in Chicago buildings.
