I have my own suggestions for fixing the "dud in the desert": Turn 3 needs to be removed to lengthen the straight to promote overtaking into Turn 4. So Turn 2 moves closer to Turn 1 and becomes a little tighter. The hairpin, Turn 6 gets bypassed completely, as there will be a straight from Turn 4, heading on towards Turn 7. And after Turn 7, the track also will head straight on towards the parabolica type of corner, avoiding to swerve to the left. That's making it a simpler track but this is meant to be conducive for more racing action.
Also, you could remove both Turns 2 and 3: through this, Turn 1 would become a corner that is two-wide which would enable overtaking through drafting (like you'd have at the first corners of Dijon or Watkins Glen or at Silverstone's Copse Corner). That would be pretty exciting. Though it maybe not for this circuit because so far, it is the prime overtaking spot.
