I told the same thing to bhanu, your struggling desperately with your line work. Long smooth strokes my friend, none of that masterbation sketchy lines. Try this, before you start your drawing, draw long strokes with your pencil on a blank sheet of paper (draw about 100 different line strokes, and draw them fast). Consider it a daily exercise, start with straight lines, then curves, then circles and back to curves and straights. I used to do that ages ago, and It really did help me get where I am now with my art. Also push more figure/dynamics and life studies.
Keep at it
