Hi Sarah!
Congrats on your EIB and I'm sure you will get your Centurion, you've done a great job.
I have a few things that might come up for you that I noticed. Not all of them will stop centurion, but they will make the suit more accurate in the end.
Your chest piece doesn't seem to have a return edge on the bottom. This might be a sticking point for centurion, Mathias has the final say, but I think looking into how to add one would be a good idea, it makes the armor sit right and looks great with one.
I love that you added the commlink and grappling hook! I thought about that, but decided I wanted to be just an average joe Hero with a TD :") Oh, on the subject of TD, it was in the works to make it a requirement for the TD clips to be all the way to the end caps, not sure if't it is finalized yet, again, I will leave that to Mathias.
How lose are your forearms and biceps? They look like they could be trimmed more to fit on tighter.
Good luck, and I can't wait to meet you and your husband on an upcoming troop! Are you planning on going to Celebration: Europe in Essen? There is going to be hundreds of 501st I'm sure, will be a big invasion!
