The debate over customs and "canons" in my opinion is pointless. Its like trying to argue with someone how chocolate is better then vanilla ice cream, no one can ever win or lose, so why argue? The way I think of customs is that its a persons interpritation of a character in the SW universe. Its somethin people have been doing since stories were first told and written. For instance, in the epic of Beowulf, you read the character of Grendal as a ferocious monster that is huge, hairy, and has tremedous claws. Thiis is where peoples interpritation come in. Some might percive this monster has a Bear like creature, or a huminoid warewolf. Its all about how someones sees things, and they do it all the time in movies. Everyone's seen all concept art, and what first thoughts and looks were before the final film came out.
So what Im tryin to say, is that customs are everywhere if you think about it. Also, its a art. Creating a character, and designing it takes as much effort as it does for famous characters most commonly seen. So no one is right to say thst customs are wrong or that they are inaccurate. Keep making art and dont worry about negativity from people who disapprove of "customs." Just keep doing what your doing.

(The world is full of characters, the SW universe is much wider, whos to say that there are only a set number of people there?)
