Other than that he’s simply drawing TIE fighters, that is?
It’s hard to believe that I have worked at Lucasfilm almost eight years, and this is the first time I have ever gotten to draw a TIE fighter.
Just doodling, or a hint at this nebulous new show?
EDIT: Filoni also released a different sketch of a TIE on Twitter:
Note that this TIE (though incomplete) has its wing struts at a slightly different angle (which, if using the regular hexagonal wing shape, would have the wing panels touch the ground at a point rather than a bottom edge). Did he realize his goof on the original TIE design and stop with the sketch… or is this a new TIE design?
