Some fans have talked about a similar kind of "swagger" from what they remember of Komarov 20 years ago, which has been quite a rare sight to see here from a teenager.
Though Kostilainen is definitely an updated version of him to fit better in the current league i.e. still a feisty character guy and an agitator who really likes to be physical and hit, go to the net for both goals and scrums, but with better skating, less pure recklessness, and no fights (yet).
Otherwise seems to have a solid shot and playmaking abilities, while possessing good hockey IQ and work ethic. Clearest area to improve is his defensive game, and a bit of extra muscle would probably be a benefit for his style of game.
This past season he started as a depth guy bringing energy and physicality for the team, and ended it with a much, much bigger role with his big hot streak in the final games of the reg. season (8gp - 7g) and playoffs (11gp - 5g2a, most pts by a rookie).
So yeah... being a one year over-ager, as the poster before mentioned, he's a possible late round selection.
