For architect, I find that to be extremely broad- especially when you start becoming a higher level and better builder. For example, being on the Gazamo build team, most of us have specialties- mine is organics and organic detailing. Not only that, but also the styles that a builder excels in. I propose more subsets of architect such as:
~Interior Designer
~Structural Architect
~Organic Master
~Shipmaster
~Terraforming Master
~Modern/Fantasy/Medieval/Asian/Futuristic/Gothic/Simplistic/Realistic/Renaissance/... Architect
There's my two-cents I don't know about the levels, but they would come after architect.
