IMG_02 : Has "straight but curved" sidewalls, 3D curved top surface
IMG_03 : Has 3D curved side and top surfaces -> towards teardrop shape -> top surface is matching to the cabin's top roof surface and extrapolated to the length of the cap. Side surfaces will taper gradually towards end of the cap forming teardrop shape yet still blends into the tail (in height) -> no increase on tail section...

Framing under is just to give a base for the plywood (simple shape)... foam on top of the plywood makes finer shapes...
