Would you mind trying my character? Seeing as I can't draw worth ****, this is the only way I'll ever actually SEE her.
Anway, here's the basics.
Night Raid wields not one but TWO wing swords, which would be more accurately described as wing scimitars. And bombs. Lots and lots of bombs. That's to be expected since she turns into a stealth bomber.
She's also a hot chick by Transformer standards, sleek and sexy. Rather than the typical boxy Seeker head configuration, even her face and head are gracefully streamlined. Otherwise she looks a lot like a typical Seeker, wings and all, just slimmer and more streamlined. Her main two colors in robot mode are black and silver, with the typical Decepticon red eyes.
Here is a design sketch for a B-2. It should be a big help.
