Wow those are awesome guys!!!
Sorry I've been gone for so long, life's been... interesting and tough to say the least but I'm good for the most part. This project is at a near standstill while I get the rest of the files in order and have them scaled to my proportions as it's not working out so well, and obviously it's a financial investment too since I've decided I will use the pieces to mold and vac form so that the armor is much lighter.
BUT in light of all that, here are some pics!
The original gun exploded LOL (no pics of that unfortunately) when I tried to support the inside with expanding foam. However, it was a blessing in disguise as the more and more we looked at it the harder it would have been to vac-form. Therefore we decided to rebuild the gun in 2 halfs and all the details (the pipes etc, build separately to attach later)
This is the gun now:

it's being resined and filled with a good strong layer on the inside to strengthen it and make the fiberglassing easier around the smaller details.
Soon I'll be reaching the bondo stage of this.
The Upper torso is also being reworked as the proportions make me look like I'm wearing a box so there's that lol
This is a VERY slow build but it is on my list of things to do.
I also have more pics which I post more regularly here:

Right now I'm more focused on getting Captain Shang ready for March Comic Con. I recently did Rufio which had great results and I also did Battle Rufio (which is also on the page).
Sorry for being away for so long, I'll be sure to keep everyone updated when i finally get this back on track.
cheers!
