I needed some details about the Qurinus station and Chris (via Meds) was so forthcoming to provide it.
I also googled a bit and found two pictures, unfortunately I wasn't able to figure out their exact source. In my opinion the better picture is boring, it's very similar to a Federation star base. The smaller picture reminds me more of the Warbird design, I think it would suit the Romulans better.
