Haha! I'll say this much and then back off the Titan issue. I don't necessarily think it is a terrible design so much as just a bit forgettable and perhaps a missed opportunity. I wish it were a bit more original. When I look at her, I don't see a cohesive starship design so much as bits and pieces of other, more successful designs, like the Sovereign, Akira, Reliant, all jammed together a bit uncomfortably. The lines and shapes don't flow into each other the way they do on the Sovereign, and the blockiness of the nacelles and weapons/sensor? pod seem at odds with the more fluid shapes of the pylons and saucer (to be fair, I have the same issue with the Akira). I just wish it brought something new to the table and had an original design statement to make. I get the physiological relationship to the Reliant and Nebula as far as a configuration legacy, but for me the various parts just don't hang together as tightly as they do on those classes. It feels like a kitbash, albeit a pretty one.
That all said, does it feel appropriate to its era? Absolutely. Is the EM model attractive? Certainly. It will make a fine addition to a starship miniature collection and look great alongside its contemporaries like the Akira, Sovereign, Steamrunner, etc. As DD observed, the more muted tones in which it has been 'rendered' as a physical miniature do much to make it feel more like a cohesive starship for me too. I was resistant to its inclusion when the EM line was smaller, seeing the place it occupies as one being stolen from some on screen ship that might otherwise not be made, but we're at a point now where this range is so epic and deep that there's room for more peripheral canon craft like the Titan and Aventine. I mean, if we're doing stuff like the PotTitanerprises and Andy Probert's concept art Centerprise, then there should be a place for the Titan, too. I am pleased for her fans and look forward to reading about how she was designed, even if I disagree with some of the choices.
But, if I could go back in time and replace the Titan with a different design that was more unique, I would so risk the wrath of the Department of Temporal Investigations. It's just a bit too referential for my taste, and that's coming from a guy who actually digs some of the older kit-bashy ship designs. I have similar problems with the STO Enterprise F design. I wish the designer had been braver.
Rant over. You'll never get me signing up to the Titan fanclub, but I am not a hardcore hater.
