The Phobos is just about the finest quasi-canon model, ever. At least I think so. It shares a special place with the Decatur and the Maguellanes for favorite Federation starships that should have been. Straight forward yet elegant designs that just look like they make sense. I hope they receive some special attention from some of our resident artists.
Come to think of it... Atrahasis's Belknap is as about much as you could ask for. There are a couple of Maguellanes that are very decent and Kevin Riley's Phobos is well done. What I really hope is, though, is that pneumonic81's Phobos finds its way into SFC. With LOD's, break model and the whole nine yards. The render he had up at Frost Works was starship art of the finest sort and pretty hard to forget.
