Neon Fox Fursuit head! + ventilation question

Hey guys! Not sure if I ever posted the completed head here, but I did some updates on her this weekend!



I worked away at her mouth to make it a bit smaller so it could fit properly when I closed it. It's hard to see, but I also worked a bit on ventilation issues, which still need to be tweaked a bit. I also added some cute whiskers I bought from Miss Matrices !
I also bought a very nice collar from her that fits perfect around my head!

I'd also like to ask how you guys make good air flow for your suits? Still having a bit of trouble with mine. :S
