but when i started to make my own japanese world war 2 era tanks i cannot belive that i coincidentally copied a piece from an already existing drawing is it stealing or can i make slight changes to differ it from the original honestly i don't know i am thinking on sould i post them as is or should i credit the artist that made the piece i coincidentally replicated not stealing copy paste .etc but coincidentally replicated it without me knowing i replicated a part that is identical to another any suggestions so i can fairly declare it mine or should i make changes i don't know as making changes will make it historically inacurate
