There are many, many very nice sets. Unfortunately, some of the most beautiful ship sets, like Slaanesh and Nostrpholo, are made in direct cotradiction to MM guidelance:

Namely, "mini" space/battlestations should be same as "portrait", NOT top views.
Besides, it makes them much better. Just compare 36x36 Version of slaanesh_portrait_spacestation with stock slaanesh_mini_spacestation and you will see my point.
P.S. I remade many shipsets this way and can send pictures to anyone interested but it would be much better if shipset authors expressed their view.
