not sure what types of tips your after, but, eyemovement will usually lead head movement when looking at something, blinking usually insn't preasant during eye movement, if the figure is for instance, going to look at something off to the left, the eyes should beging moving first, followed by the head, and the eyes should return to center after the head is facing the object, save the blink for the very end, although sqinting the eyes, or widening them would not appeare unusual during the movements. hope that's helpful :)
