My skills as an artist

I really enjoy all kinds of art, but drawing is my strong point.  I prefer to draw still life and portraits rather than imagining things in my head and then drawing them.  My weakness in art is the use of color.  I prefer to do all my drawings in just pencil, but people always tell me to color them, and I just can't do it so it improves my drawing.  For sculpture, i haven't really had and real experiences with sculpture so i will soon know my strong points and weakness's.
