There are very few spectres on Mocpages...by far this is the most accurate, and clean looking one yet. Only flaw is he seat cover on the front. I dont know how you could fix it, but still, it looks amazing!
Not many people have ever made the Spectre out of Legos, and even less build very good ones. Needless to say, I really like yours. Nice attention to the geometry, it's very curvy and Covenant-like. Cool engine, too.
