Scaling after 1 month debut

Hey everyone, I launched my first novel a month ago, it's had decent success and even some reviews. However, as with any business I'd like to scale. I'm talking with a couple book stores to put it on their shelves, and I'm currently working on a sequel although it will take some time to complete.

I don't know many people in the writing industry yet, although I had a couple alpha readers (friends and family), 9 paid beta readers across 2 rounds, and I invested in a high quality cover.

Based on your experiences, is my blurb strong enough or could it be improved? Does the cover match the genre? My book is very graphic and gory, even for a dark fantasy, so would marketing it as splatterpunk or grimdark instead of dark fantasy help? I don't want to attract the wrong readers.

Blurb:
To destroy a savage cult and survive a bloody war, an eighteen-year-old Demon must master the fiery powers of a grinning mask.

Cut off by his powerful grandfather Subnekros, Prymos Virtex is a hotheaded outcast desperate to prove himself in the deadly kingdom of Kozmorros. His moment comes when he seizes the sneering Vicious Demon Mask—a dark artifact that finally awakens his Pyrokinetic abilities.

But Prymos’s reckless crusade ignites a feud that consumes the kingdom. His violent rampage puts him in the sights of the Sanguis Dei, a militant cult commanded by the sadistic Lord Nazawrath.

Left permanently scarred after being captured and tortured, Prymos must kill Nazawrath and exact his revenge. If he fails to save the kingdom, or succumbs to his inner demons, he will suffer a fate far worse than death.

Game of Thrones meets Invincible in this gritty, action-packed dark fantasy.
