Some of these mods might not be to everyone's taste but it addresses a few things that bug me. I always found the "wasp thin" waist and the bulk of the wings a little off-putting so I moved the roof/windows to the back. The windows still fold up and the roof hugs the back quite nicely. I know it now gives BB a backpack but BB's torso is bulkier. The hands are on temporarily. I still need to completely remove the screw post and then the hand's ball joints will snap in snuggly. The hands stay on in car mode. The thing i'm scratching my head over is how to compress his chest even further in bot mode. And I would not mind a solution to the clod-hoppers he's wearing.
