Very nice! Are they all mostly Styrofoam? your own templates or online? I myself have only done the assault rifle (I used a sliced file and EVA foam for mine) Keep these up.
Looks like you're gonna need a bigger wall lol. All of those look fantastic! And dare I ask what is wedged into the corner over there? I see it has a bayonet, and the only thing I think it might be is Lady's rocket launcher from DMC 3.
Why yes, indeed I seal it. I seal all my styrofoam props in about three to five layers of Elmer's white glue or PVA glue and apply it with a small and medium sized foam paintbrush.
So this is a bit different from what I usually post, but guess I'll share it. A while back I was working on a red death pulse rifle for my Destiny warlock cosplay. Here are the progress pictures.
Here is what the gun looks like.
The magazine reloads!
Added the bayonet and spikes. Off to paint!
Here is the finish project.
I know it doesn't look that great, but it was a rushed project for a con. This was the first time I use EVA foam with my typical styrofoam builds.
