Reference aren't bad it a amateur missconception that people who draw can invent from there head directly into paper and that people who use reference are just newbie this kind of viewpoint is detrimental to artist who want to progress.There nothing that prevent you from being proefficient at drawing from your head if that what your inspiring to do but the general rule is not to be married to the reference as to avoid copyright infringement it can be hard at first for artist to determine this kind of thing since there little to no way to determine this the rule of thumb is to change it enough that there no way to tell.
