2, the forehead is small, you can try to cut your hair short and try to expose your forehead. If you don't like short hair, then you might as well grow it long and cover your whole forehead.
3, the nose is big, you can pinch the nose wings more and dig the nostrils less. Stick to it for a while and it will have some effect.
4, dark circles. Stay up less and get enough sleep. Before going to bed at night, you can add water to pearl powder, stir it into a paste, apply it to the dark circles, and wash it the next morning.
I wish you find confidence and love as soon as possible.
