Heeeey! I remember that ship! As a matter of fact, I still have it. I also have your Beaous Aries Class Heavy Crusier and I performed a test kitbash with the model to make an Eagle Class Lilght Crusier. These two models help inspire me to learn Milkshape so i could make my own models.
Heck, I'm even thinking about using some design concepts of the Sirus class for SFB style X-ship classes I have in my head.
By the way, I like new engines, but I didn't mind the Ramp Scoops being more round like in the first model. Anyway, great to see you wanted to continue modeling.
