I've done a few searches and browsed through various forum categories, but haven't found what I was looking for: on many Lego boxes and instructions you can find photos of alternate models, without building instructions. These are meant as "inspiration", to get you spurred to build your own creations, possibly while trying to reverse engineer the builds on the photos. Is there any place on this forum dedicated to these "inspiration builds", where people can post their variations, discuss their troubles while reverse engineering, etc.? Also, what would be a good place to post this question in the first if not in this practice forum?
