Between the wheel pants, gear, helmet, nav lights, and canopy is where you have allot of polys invested. Instead of banding the fuse with edge loops below the canopy you could terminate those edges by making the canopy a separate piece of geometry. You could select every other edge loop in the nav light and wheel pants and dissolve them. I count 58 polys you could gain by dissolving the edges that horizontally bisect the wing tips. I cant see from the pics but it looks like maybe there are more sides then you need in the cylindrical geometry around the air frame. All that said your toucan is looking great Andy. Your a natural.
