Welcome Patrick.
Thanks for posting these, it is very useful to see how you removed the suit.
Still, I'm not sure I like the result, in my opinion the torso and legs now look too skinny and they looked great out of the box.
Just compare the arms to the torso on your picture, the proportions are now off.
Bruce Wayne would have to be extremely skinny to look like that with the suit on, this is Batman not The Machinist.
I believe that Maglor's idea of adding material under the belt section instead of removing the fatsuit is the way to go.
