Art - The naked Women

The naked women~~my second drawing, i am not specially keen to draw the naked women but i don't how to draw the clothes when they putting on, i meant the natural lines, shadow of the fabric....hai..the facial contour is weird, dont know how to improve. Somebody can teach? or any opinion?

my 1st artwork(drawing)

Normally, i meant in our mindset, only the children or teenager willl join the drawing class...well, i joined the drawing class at this old age,at the age people suppose to work hard for their "career"..to fulfill what i wanted when i was still a child. So how do you think about my very first art work? I make them into different colour to represent different mood and character. Life is bored, at least for me, less of determination to complete various pieces of stuffs. Drawing, perhaps can fill some colours into my life, and concentration, to temporarily forget about the soreness in my life. Do peace and cheer re-gain!
