I'd have to say this drawing is great. I love how you made it where the 2 characters are not exactly entwined but almost like on top of each other(nothing perverted wise). the shading on Shadow Ragna is lovely. I think maybe on Ragna's green mane hair maybe you should darkened it a bit and made the lines in a bit darker than what they are(unless the scanner ate the coloring but thats possible too). I like how the pearls aren't exactly circular but still look like a pearl shape. The pose of the 2 characters is awesome.It looks almost like Shadow Ragna is going to bite someone's head off or something. I also love the mountains in the background and with the red and orange sky it almost just makes everything else just pop. I've always loved how you do the backgrounds in like a border kind of way. The paws look great on them both of the characters. The way you shaded Shadow Ragna it almost looks like she's skin and bones. Love the cracks on the pearl and Shadow Ragna's beak. I think maybe Ragna's tail should've been a bit straighter but thats just my opinion. I hope thats a bit of help.
