I have been researching a new render and modeling style that reads as hand drawn... I will be using this style to make the next months challenge and look forward to making a tutorial at some point.

Here are some examples there are created entirely in c4d with no additional photoshop except for the ones with the signature.

Let me know what you guys think, and I will keep you updated on the style as it develops!
