That's exactly right. In fact, the only area on mine that is detailed where the original is not is the starboard side of the bridge. That was a decision I made back in 2008 when all I had built was the bridge and wasn't sure if I was going to ever build more than that.
Actually, Eric did the same thing with the lack of starboard guns on his SD...

I'm a big fan of his work, and his star destroyer build inspired me to build this third, more accurate model than my first two attempts.
