I'm not contesting anything.
I'm DESCRIBING what's IN THE ARTWORK.
Are YOU contesting that the front legs and wings ARE divided? Because they're clearly, you know, not. Solid white interior from the front legs goes over into the wings seamlessly. That's... fact. Right there, in the picture.
A counter to WHAT?
YOU are the one claiming Tolkien's dragons have 2 pairs of legs and separate wings. You provided one drawing to back that claim, but in that drawing, the front legs and wings are A SINGLE UNIT, not separate.
I'm happy to refute your evidence if you present it. I've refuted one piece of evidence (that picture). I'm happy to look at more.
I'm also happy to make a counterargument if and when your initial claim (Tolkien's dragons have 2 pairs of legs and separate wings) is actually DEMONSTRATED TO BE TRUE.
Until then, the burden of proof is on YOU, not me.
