If you look at the charts in the background, you'll see that my MS Paint skills are nowhere to be found on them. They are, indeed, off the charts. Wildfire belongs to Sibsy: [link] Fausticorn belongs to Fyre-flye: [link] Background from: [link]
Awesome. I presume the other one is the Fausticorn yes? ( Noticed you only gave Sibsy Credit )
She better be careful, her drawings might burst into flames around Wildfire .
On a side note, nothing big but a bit nit picky. Celestia's Younger self had an all pink mane and tail ( and technically her wings, but nopony ever seems to draw her wings pink ). ( Now that we might get a backstory on Tia and Luna I hope to see an official look at Celestia's younger self. =3 )
According to this book's style Luna's wings should be a lighter colour than her coat, and her mane/tail an even brighter shade than her wings. It also says Celestia and Luna have the same tail styles. According to the proportions of the second panel Nightmare Moon's pupil is supposed to be slanted forward ~36 degrees, and her flank should have no purple blotches with a cyan crescent moon on it. Final panel says Celestia's wingspan magically doubles after all of this for some reason.
