Hi Xeon,
Amazing photos, looked very realistic. Don't pay too much attention to the photos (though we tend to) as in photos our forehead will appear wider and higher. Yours is very nice.
I usually tape my poly and thin skin with glue at the front and tapes all over (not strongest tapes, of course). Very solid for 5 days (no lift at all). The reason why I use tapes and glue mainly because I work out very vigorously (more than 5 times a week). I've always tried to remove it whenever I feel like (when it gets a bit irritated or it stinks). Will not feel safe if not attached with tapes or glue
Thanks for the nice photos.
