Of the pictures...

Her Hair. Well that lone pic of the redhead sums it up... though it's more like Alielle most
    of the time. It is a violet color but more royal purple than Alielle. Hopefully this doesn't
    still look like Ruckus from Fanboys! I've had to change her looks about a bit since then...
    don't want to contemplate the thought that Astrala will look like Ruckus when she gets
    older -or act like.
Her face is a bit of a toughy... she's facially looks like the lost cousin of Sasami and Skuld.
    What that looks like I dunno. In a pinch use Sasami in your mind :) Minus the head triangles.
Her everyday wear runs mostly to school uniforms. She says it's a bad habit she can't get out
    of. Green and Black motifs usually. She also has a stock of kimonos she isn't afraid to wear.
Her measurements she is able to change on a whim but usualy fall in the not quite ripe catergory.
    What the numbers are for that... I dunno...
Her personality is pretty much stock bits of Sasami and Skuld depending on if she is being
    picked on (Skuld) or complimented (Sasami). When she's feeling lovey dovey she is plagued
    with fluttering hearts and heart eyes. She doesn't however "glomp" like Alielle does. She's
    more of the sigher.
If she were a model she would pose like...
  • (ecchi) Probably a Kitchen scene with her in nothing but an apron, or her dressed normally and leaning over a pot with her panties showing... OR (last one I promise) her wrapped up in the frilly blanket her and her sisters share space under at night
  • (silly) Dressed up in her Pretty Sammy Costume from the one Omake with Noh'Ohki hovering next to her posing with her Sammy Baton
  • (serious) Cracking her knuckles with a toolbelt riddled with tools from the kitchen and garage stalking down the stairs grumbling.
  • (shopping) A nice kimono that has the sense of modern as well as old, or a school girl outfit if groceries.
    • Also of note like her pattern-afters she is a whiz in the kitchen (Sasami) or the Garage (Skuld).
        She also plays a Mean game of Street Fighter (Which version? All of them... she's like a... demon ^.~ )
        She also hates getting picked on.
