I have yet to see a good and creative artist that does not use any reference. Sure those, who do same character 100th time for their stream may eventually not need one, but that's not very creative either, now isn't it ? A reference can be something simple or something complex, but use of them will improve your work. Seen plenty... a lot of beginner artists, who start lecturing others how use of references means you are bad or something. I am not even going to type down what I think of such statements.
I see some artists use it as badge of honor, "I used no references at all" - I often am tempted to respond with, "and it shows"
I use them - I.e use often unreal mannequin in blender to pose for me and stuff like that. I think quite few beginner artists think that reference means copying an object. No, no a reference often is something else like how material acts, how a pose is, how perspective is, how light may be, how a flora looks like and so on.
