The first time I draw a woman in Oda's style I was happy but then I realized that I based my drawing on Nami, too much (year 2007?) ... so I desisted. I didn't try until 2011 and I decided to improve. Anyway, I hope that my studies captured in this short tutorial, can be of some help ^^.... REMEMBER I'm not a pro so there could be mistakes. Thanks Jeany for the support ;3FINAL NOTES:
We know that Oda has many surprises for us, the faces of women that he makes are reaaally varied (features and shapes) So the study doesn't end here!!! keep practicing and never give up!
Just one more thing
