I thought that your work was fascinating since I first saw it. And I'm not one to just say that easily, and I am one to say what is is that is a bad idea or state that something should be improved especially to someone who's work I respect ( otherwise it wouldn't matter to me) so here goes,
The neck angle and fork angle doesn't flow, makes the entire machine look broken to me.
The front fork angle to the neck , looks like the top forward connection could go at least 1 bolt hole back , in essence , mechanically extending the rake, but I'm guessing that would change your spring ratio probably making the ride really stiff.
Like I said ,I'm a fan of your work but me thinks somethings a miss. Respect RB
