Geisha Stamp

So this is my first Illustrator piece; we "learned" (more like fumbled around crash course style) Illustrator in class and had to come up with a stamp design in our selected theme. Continuing the theme of butterfly and its symbolism, the subject is the geisha girl and how the Japanese often refer to women as butterflies. I used color references from art prints I saw.. ^_^ I really would like some comments since I'm kinda new to the program, etc. ^.^;; I tried to improve the stamp based on class critique and after looking at it, I kinda wonder if the branch in the bottom right helps cut the negative space better or just busies it. Also, I might've added too many butterfly silhouettes....let me know!
