Well, I will just say first that this art is fantastic. Every detail of the princess of the night is just immaculate. Each feather on her wings is just fantastic, and the layering effect there is awesome. I like the way her expression is kind, yet still vague enough to be mysterious. What is she thinking? Each viewer can say for himself. Which reminds me, her eyes are amazing. The detail that went into each shine is prefect. And as for my favourite part, that has to be her mane. I have no idea how you managed such a gorgeous pattern on her mane and tail. Just stunning. The setting, with its warmer colours, complements her nicely. You must have studied a picture of the Canterlot castle for quite a while to manage such an accurate silhouette. Positively fantastic.
Very well done overall.
