This is a faithful adaptation of Dune into a graphic novel format. As is typically expected from detail-dense, it loses some of what's in the novel. I do think it does a great job of hitting what needed to be hit, though. 

The artwork isn't quite as stunning as I had expected. It's good, in my opinion, and it's certainly better than a lot of novel-to-graphic-novel adaptations that have literal pages of text or panels just filled with black-and-white text. 

There isn't a ton to critique as far as the story or characters go, as this is a faithful adaptation. The art and pacing are the biggest parts with and change. The art is discussed above, and the pacing isn't bad. It's not perfect, but it's really hard to pace half a story. I feel, assuming the same pacing structure is maintained, the whole story will be well-paced.

I'm not sure I'd recommend this to someone who hasn't experienced Dune, though. Similar to the movie, this is only the first part, so it feels incomplete. And really, Dune doesn't start fast, per se, so just having the first part of the story is a disservice to anyone coming in without any Dune experience. I would highly recommend this to people who have read Dune. It's a great adaptation in that regard, but I'd hold off if you haven't until the entirety of the first Dune is adapted.
