Girls girls! and more girls!

Hello Hive friends, these days I have been practicing a lot what is the portrait or illustrations of girls' faces, it seems to me that the woman's face besides being the great muses for the best works of art, is one of the things harder to draw because you must have a certain delicacy when drawing the lines to make them look like what they are, girls. Well I leave a little of the step by step of this illustration I hope it is to your liking.

Thanks.
