Even when its projected onto a model, it'll look weird. It should have a hose on one side of the face and a filter (or whatever it is) on the other side. Yours has the filter on both sides.
WIP=Work In Progress.
If I was to make the model and UV I'd make it only for one side and just mirrored it to the other. There's no normal mapping so tangent/bi-normal vectors are not important, and you can have virtualy double sized textures this way. Both the filter and the tube would have its own geometry and a seperate UV that would be later merged into one texture. The texture for the mask needs to be projected from the front and the the rest of it wraped around (or the oposite if you want to have the seam on the front). The details like the filter and tubes need to be wraped aroud by a texture two but at a diferent angle, along its local Z-axis (in z up). But you must know that, since this is basic stuff.
Anyway, keep yer pants on, I'm not doing the mesh, I'm not doing the texture. Maybe I'll help later if someone will ask me to.
