One thing I’m happy to have discovered is that while Hasegawa offers the intake as two pieces, with a corresponding seam, the actual intake has no such seam, so I’ve filled it with surfacer and smoothed it over. Some modelers seem to catch this, while others don’t, and I almost missed it myself. I've also filled the area where the venturi is located, as this aircraft apparently didn't have that mounted (still needs another spot of filler though.)
It's also apparent in this photo that cowl needs a bit more sanding to correct some minor fit and shape issues.
