Decided to make a new thread, as the old one was getting a bit too cluttered.
This is my main reference:
Right now I'm setting up the materials but I'm probably going to rebake everything because I forgot to include the glass in the UVs. And hopefully I'll get some good feedback on things to fix. Haven't baked AO yet because it takes a very long time to do on my shitty pc. I think the helmet could use some more geo, but I'm already at 17k tris with the fur so I'm not sure if I should.
