Thank you for the ask!

While I was drawing Queen Twilight I went ahead and also did Princess Twilight. Instead of wearing a full crown all the time, I thought she’d wear a little comb in her bun with the spark of magic and only wears a crown/diadem when she becomes queen.
For her queen form I tried to reflect the both the night sky and magic in her mane (the purple bits are a bit more firey ig)
I don’t really like the weird breast plates the princesses are wearing, so I went with simple jewelry, as I don’t think Twilight would like to wear too much (or anything flashy)
