I like the clay render of the model okay, a lot better than the drawing. To me what this really lacks is some explanation of this design. After the Sov, Prometheus, Intrepid, etc. it's clear that Starfleet has ditched the interhull concept connecting drive to saucer section. Why have it on this ship? More importantly, how could having it split like that provide any benefit?
Also, from the drawings, the ship looks a touch to gregarious for my taste. It lacks refinement and sophistication, if you catch what I'm saying. The modeler from STO said he took inspiration from Porsche, but it looks more like he took inspiration from Volkswagen... quirky and nubby instead of slick and refined.
Though as I said, the 3d model is promising. My biggest gripe right now is actually with those terrible nacelles. It's fun to try to make nacelles look "advanced", but in the end look at every canon ship. The nacelles are usually pretty simple, pretty plain... One should not disregard practicality in their design. Remember the crew only sees the ship one room at a time.
