No cutiemark on Twilight because I am lazy — but! I felt like drawing Starstruck and Twilight, at a time where Starstruck was still a total mummys girl and fawning over her mother.
This takes place shortly before Twilight gets romantically involved with Sunburst.

As Starstruck grows to be about 6 years old, the two grow more distant, and Starstruck is reluctant to bond with her mother — ofc it doesn't help that Twilight gets another foal, a unicorn foal, whom she fawns over and loves to bits.
