Firstly, I'm a heel for not having pictures for this at the moment, so I appologize, but it's so simple and self-explanatory that you may not even need them. Look at the underside of Bumblebee's chest. See that vertical ridge that runs down the middle? See how it fits into the groove on his waist/stomach area when you fold the chest down? Well, if you shave that ridge down the chest can go down further and get closer to the body. Why do this? Well, if you take off enough of the ridge you can fold down the chest far enough to get rid of that gap beween his head piece and the hole on the hood that it goes through. It looks a LOT better when that area is flush. Also, with the chest folded down further it doesn't stick out as far which to me looks better. The only drawback is that it covers up the details that are sculpted onto Bumblebee's waist. Your mileage may vary as to weather that's a sacrifice or not. And, naturally, if you are going to try this you should use something nice and sharp (my Leatherman Micra blade can cut through adamantium) and work SLOWLY, taking away small bits at a time so you don't take off TOO much. But don't worry little shaver, even if you do take off too much and the chest goes down too far, there is still enough friction on the chest piece that allows you to position it pretty much wherever you want it. And since you've got Bumblebee under the knife, if you haven't done the knee mod yet you should do that, too. But weather or not this little guy is even worth modding at all is up to you.
