? Color of the hair and eyes is too light for an Italian, particularly for Sforza's daughter. The girl looks rather northern European (German) than Italian
? Neck is too thick for LDV proportions (check the overlay photos from here: http://www.3pipe.net/2011/07/enhancing-art-of-seeing-leonardo-case.html
? Lower eye lid looks wrong - horizontal part is too thick - looks unprofessional
? According to LDV theory advocates the carbon analysis puts the probability that the velum existed in the period of interval 1470-1530 is 27.2%. But "La Bella Principessa" died in 1496. That will bring this "probability" to less than 10%
? All noble women in the Renaissance portraits (by LDV and others) wear jewelry - not "Principessa"
? GC/MS and MS/MS analysis of the pigments (not velum) from "Bella" should be compared with the LDV's proven original pigments to be able to have any significant data for publication in scientific journal
