IMO he doesn't need to stop - he's learning to build complex objects rather fast - i took more time than him making my first scene to be uploaded to phunbox1. the difference is that he uploads what he does on algodoo, even if it's not that good if compared to other ones.
this guy has a great potential to become better at making scenes, but he might want to use algodoo's newest version, 1.8.5, for that.
