I've built a few smaller boats with family, I have boat and ship builders and designers in my family and I can pretty much say they will complain about the shape of the bow for sure. A straight bow (or a plumb) is terrible for rough seas as it tends to pull down into oncoming waves. As for the flat chines, let's hope there's a decent stabiliser in the hull otherwise that's going to be one vomit inducing ride. As I can't see the total draft it doesn't show any tech below the water line. There maybe external stabilisers a couple of meters below the freeboard.
I'm not a big fan of the high transom, I can understand the amount of stress that happens in that area, but from what I can tell, the structure shown seems to indicate a drawbridge extending out of the back so there must be a fair bit of reinforcement behind all that sheet metal to deal with the torque.
To be honest, it looks more like a river cruiser than a blue water international cruiser. Maybe he intended it to drift around a local lake?
