The mask looks great, and you dont look cross eyed. If you want to fix that problem if it bothers you to much can you put a stich or 2 on the back side of the bridge of the nose area to pull the mask tighter in that area? To me it looks very flat against your face and I think thats why you get the cross eyed feeling. Im sure others will ring in with ideas that may work better.
It does just look as though it's a bit too wide across the bridge of your nose, so perhaps you can trim the eye openings so that they're closer together?
