It's neat to see some people actually interested in exploring manga as a medium, and not just as an idea ;v
surprisingly, a lot of people call their work manga and don't incorporate a lot of the same techniques used to create the comics. There are surprisingly few.
I have a manhwa called City of the Sun. The story is about a zombie who is looking for a mysterious monster haunting his past. It's a supernatural drama with horror elements set in the deep south. No silly, romance esque fluff- If you like action and drama featuring monsters, men eating vampires, and our lord and savior Baron Samedi, this is the one for you.
