It’s clear to me that Starlight Glimmer and Sunburst are infatuated with one another. Why else would she blush when talking to him, and then him blush as well in episode 2?
 
Not sure if this subplot will be pursued, but what’s been revealed so far is intriguing.
 
I really like his color palette, and that cloak looks perfect on him. This is the second stallion I’ve done and he was a blast.
 
Edit: Fixed an issue with his chest/cloak.
 
Edit #2: Improved the shape of the tip of his mane.
 
Edit #3: Corrected his cloak again, as it wasn’t tucked under the buckle.
 
Edit #4: Touched up his cloak crease.
