I dug out the pic of that thing...my first impression was "meh, pretty square and boring." But I got to thinking about it, and that might be a challenge in itself - to take some of those early simple (and moderately ugly) ships and see if you can make them visually appealing and useful.
The listed size is way wrong (8.2 m x 8.5 m x 66 m = 4600 cu m = 328 dtons), and I haven't checked the validity of the design, but I took a SWAG at a prototype over morning coffee, built out of a box and some pieces I had laying around. Scaled up to get the right volume it comes out to 12 m x 12.2 m x 94 m. You can see a rough render of it here -

It looks primitive, boxy, pretty uninspired and poor. Kind of like Steve Cole's "star trek" drawings for his SFB Game, which are some of the absolute poorest sci-fi renderings I've ever seen anywhere; worse than fan art kind of bad.
Eliminate that huge sensor dish. Give it some sleekness. This is 57th century tech were talking (allegedly). Get rid of anachronisms.
