AV - I like it -- A LOT! I do have one suggestions though (actually two...)
First - I know you are trying to stay true to Atolm's design, and I really admire that, however, could you do a version with a smaller nacelle - and mount it on top vs. the bottom. I'm a pilot in real life and I think landing this thing on any planetary surface might be problematic with the nacelle on the bottom. If the landing gear (or anti-grav pads) malfunctioned she'd be hell to land even on a prepared surface. Something would break unless she had tractor beam support from a mothership or ground station -- which could be an issue in combat. If you want I can help with that version. My bashing is getting better.
Second - Asymmetric Atolm mesh in the works? Ya' gotta show us! I think I know the sketch you're talking about but I'm dying to know! With these little babies on board she'd be formidable. Maybe she'd a good entry for the Darker Projects 1701F design contest - retro yet modern and can't beat Atolm's originality. Especially when combined with good modelling and meshing skills like yours.

Nice work and thanks for sharing.
