Renders are not useable sources.

5.6. 3D Renders or Illustrations as Source:
Using other people's 3D renders or illustrations (even with permission and no matter in which form they are offered) creates a false impression of your artwork. So 3D renders or illustrations can not be used as sources, unless they are entirely created by yourself. Only acceptable non-illustration brushes and clip art may be used, but you need to mention them as a source too. Don't use an image that has been altered by the source owner nor an entire work created by someone else.

The use of 3D wireframes or mesh has always been allowed. The author did not use 3D renders but rendered them using the wireframes to create the final image as is shown in the SBS.

5.7. Models Created with 3D Programs such as "Poser":
If you use a 3D program to create a model or render (eg. with Poser), post a screenshot of the wireframe, so we can verify it's not someone else's work.

Congratulations... nice job...!

Congrats Randy!!
