I like the Ambassador.
It is a perfect blend of old and new design aesthetics.
I think many negative opinions come from the fact, that the model was low on detail and up until now was only seen in low rez fuzzy pictures.
Cryptic's version lost all the fuzziness and has more details but is even more low rez.
Keep the general shape, photograph it in HD and use a model with the detail levels of the Ent-D and it is a very good design.
This is why I'm looking forward to watching Yesterday's Entrprise
when it's shown in HD next month. The Ambassador should look fantastic.
I think I'll see how much it is before I try flying one - I think I want the Vesta-class first.
