For me, lowered eyebrows, narrowed eyes, pursed lips, and perhaps a<b> heightened colour</b> would suggest "an angry look".<br/><br/><b>Characteristically</b>, the head is slightly lowered, and the "angry look" is directed from under the eyebrows.<br/><br/>What does the "heightened colour" and "characteristcally" mean in this context?<br/><br/>Please help me.
