That's plainly not a Star Destroyer, and the Pixiv page makes no mention of Star Wars either, so tags removed. That's just the Unidentified Fantastic Object.

If that's a Star Destroyer at all, it's a Victory-class. It's the only SD class that is light enough in starship terms that it can feasibly maintain flight in an atmosphere using repulsorlifts. The Victory class is even DESIGNED for planetary assault, having the best bombardment rating of any ship in most Star Wars games when it appears.
