@slowwalker,
Yeah I also thought "Mireuk statue in Daejo-sa temple" is much similar to ordinary men's faces! But like you explained later "Mireuk staue in Ghanchok-sa temple" is far beyond the ordinary! So people definitely like the statue of Daejo-sa temple!
Anyway those stone statues of Korea are unknown to us till today! So, it's great to see such nice photography and explanation why they were changed from each others! Thank you!

Cheers~
