Hey matt, yeah i was thinkning of starting this myself...thats pretty damn amazing for the time you had...and distractions. Think the hovering motion is excellent and the movement of the ship as the legs and gun pops out.
No sure if its the effect you're after but when the turret, comes up its almost as if there is excess room between the outer ship and where the central turret meet, giving a kind of oldish and worn feel to the movement. If this is the feel of animation you're trying for then excellent, dare i say it but overall its looking like 'wild wild west' gadgetary. Nice work...
