I'm glad you like it. When I first had the idea to make the AU puddlejumper a mechanical animal that thought was immediately followed by "but that would never fly for real" but then by "it's not like SGA is hard SF in canon", so I just went with what looked cool and was fun to draw. Though I did look at lots of reference pictures of historical machines and their parts, and steampunk tutorials to make it look like it could exist.
