I wonder if there should different grades for the 'muscle' tag, like the breast size tags. 'Cause there's line one ab per ten images here and apparently that's enough to warrant the tag?
Some of the stuff seems to have gone down in quality. Look at the face on Hestia (p11)- it's pretty poor even compared to the FFVII (P38). Almost like a different artist copying the style, or an artist trying to evolve their style.
