Flight of the Pelicans - "Taking a break"

Initially a workflow test with Fusion360, Blender and Photoshop. The seaplane from my flight of the pelicans serie became the test-subject :) Still figuring out how to retopo a CAD/SOLIDS mesh fast enough to even consider doing it during a stressed production, just do it by hand, or use any auto-retopo from 3dcoat/zbrush, or buy Moi3D and use its OBJ export...Would love if anyone has any good knowledge on the subject in matter.
