hi hu-man!
i haven't had time to much play with illustrator myself (hope to get back w/it next year!), but it looks like YOU're off to a good start!
her shoulder bag (purse) looks like it could use something.
being almost the same hue & shade of the sea, it has this negative image look right now. (to me anyway)
is she holding a pair of sandals? if so, some indication of straps might help the viewer to understand how she is holding those shoes...
keep on rocking the vectors & please post your progress!
