I think the problem lies not in my fascination with flat surfaces, but rather amount of details to ship size ratio.
Basically when you look at Eclipe you got sensory overload and you don't see ship and it's elements, but a slab of various shapes and colors:
Honestly - if you would have seen EA ship for the first time it would be like - where are beams/turrets? the red thingy? cyan thingy? yellow thingy? big grey cilinder in center?
Turrets on top barrelly distinct from hull elements. The hull details are severly distracting in Eclipse case.
Let me show you other ships that follow the very same design, but are bigger:
Nearly exact same design principle, but somehow much less chaotic (still a bit too much to my taste, but way better than Eclipse).
Tereus actually looks very good and there is even some flat surface that nicely ballance the hull details (Same is with Lindos).
All 3 ships seems to have comparable level of details, but Eclipse is the smallest of them, which makes it too detailed per square meter of surface.
