For me, lowered eyebrows, narrowed eyes, pursed lips, and perhaps a heightened colour would suggest "an angry look".
Characteristically, the head is slightly lowered, and the "angry look" is directed from under the eyebrows.
If you ever come across a copy of Darwin's The Expression of the Emotions in Man and Animals, you will find some interesting analyses of "angry looks".
All the best,
