the stencils in the second picture look pretty clean, but the top ones are messy and it looks to be a gasmask(yawn), i'd try to clean that stencil up and make it a little more detailed.
btw, what is there to bite? seems to me you havent doctored those images in any way so i don't know why you think these images are yours. i've seen plenty of all 3 of those stencils.
