I don't mean to sound like a jerk or something, but this is probably your worst picture of Noodle I have seen, not saying that your a bad artist but I think your earlier pictures of Noodle are way better.
I do have to say that it is a bit different from the other drawings that Psychoon has done, Noodle in this case looks a little different to me compared to the pages of the comic: Her hair is mid to her eye instead of being able to completely cover the eye, Her cloths, well it looks like she is wearing 2D's "Sudden Impact Driving School" jacket, just does not normally match her clothing style, given from Psychoon, Her chin is a bit smoothed up, She looks a bit younger than she really is, yet her left hand may be a bit exaggerated in size for her age. The size seems to vary among all of their hands, And Murdoc, well, his teeth are dulled (thank goodness...)
BUT, ANY WAYS... It all looks fine and good to me.
