it will be nicer for you to post the image here rather than a link.
if i can comment on your turnaround i will mention a couple of items. first, you should probably work on defining the drawings more. some lines are vague and incomplete. a turnaround needs to communicate details to someone else.
second, you have done something specific which drives me crazy when i encounter it. if i meander on a tangent, forgive me - i don't mean to project other peoples faults onto your image, but i see a trait on your image which is becoming a very bad and common habit in character design. define in your mind the difference between an illustrator and a designer. an illustrator can tweak and cheat attributes to fit a scene, mood, attitude. a designer needs to stay clear of attitude and simply create the physical character. the little trait on your character which bothers me is the mouth. it may work as an illustrator to have a skewed mouth (front view) in a comic panel, but in the design sense it comes off as irresponsible once we look over at the 3/4 view. if the character is meant to have a skewed mouth, then solve the visual problem of defining how it looks from different angles rather than leaving it for the next stage of (a theoretical) production to battle with... i have encountered and was required to fix new-type comic book style of character turnarounds where the initial 'designer' could do one angle seeped in coolness and attitude while the other views fell apart - mouths especially keep moving to sides of heads, change in size, go from an underbite to an overbite etc... take the role of 'designer' rather than 'illustrator' when doing turnarounds - you aren't drawing pictures, you are creating definitions for the next stage.
