The basic step-by step drawing guide that follows
Create outlines of the shape you want your daughter to be.
Create a bikini. Then, make sure to add a bit additional leg.
A little tweaked the lines but not too hard. Draw your hip bones, your navel and a few additional bikini lines and a couple of detail lines where you’re looking to make the look more real.
Make use of your pencil to draw lines on the darkest parts of your body (I refer to where you want your shadows).
Make use of an eraser to create the contours of the body appear lighter. Recognize the excess chest, belly the hip, and chest bones. Darken bikini lines.
Mix it up again.
Start coloring the bikini darker.
Mix the bikini in a well-organized way and add more shade the body, if required.
Make use of the eraser to put some light to the chest, shoulders and the hips. You’re done!
