This is my Gruuuunt~ He's such a big boy haha. I'm making a silicone mold this week and then.... eventually when I have an income again, I'll be casting him in FlexFoam-it X from Smooth-on.
Casts of this mask will be $150, or $200 fully painted like the Krogan of your choosing.
Since I have yet to make a cast, however, if you would like to fund my trial cast, the cost would be $120 for the supplies, and I will include a full paint job.
This thing is going to be one hell of a cosplay!!
