I would say even the sensor dishes don't really make sense. They look like they serve a function, but it's only the appearance of function. Take the Barah'tok, for instance. It has two massive dishes on either side. We're made to assume that it serves some purpose, but they're not really positioned in a way that makes sense.
About the painting, Archaic. The artist generalized a lot of the forms. It isn't all that aparent at first glance, but there are parts that do't make sense, or are inconsistant. That is what its supposed to do, since the viewer fills in the rest with their mind, the ships actually appear more realistic than if all the details had been painted. A lot of the Impressionist painters did this, and it makes for a great painting. However, it means that what works well on the canvas doesn't work well in the round.
