Going on the record - I'm just not liking the Titan A design at all. Looks awkward and clunky.
I kind of like that. Starship design has been all sleek and pointy since John Eaves became the predominant starship designer. And that's great, but I also like a bit of variety.
It's nice to get something that looks a bit more chunky and modular. I can easily imagine a Reliant-style counterpart to this ship. Or versions with four nacelles, or just one.
