I like painting female characters as I feel that there is a lot that can be done with them. They can have some very nice dresses with lots of folds, wear lots of shiny jewelry, ,can have some beautiful makeup on to enhance or highlight facial features, and can have some nice flowing luscious hair. Unfortunately, being male, I can't always use myself as reference and I won't necessarily always have someone nearby handy to be my reference. Here is a great, fun, and funny tutorial by Meghan Hetrick on one of the aspects of females. How to draw boobies.
