1. I like more fashionable reusable bags, and least of all, ones with too earthy designs.

2. If it is pure black with white words and patterns, it will be more eye-catching

The yellow background with black is more convincing, I like it (you can refer to the "Beware of Bears" brand design )

If the white background + black elements are more harmonious, simple and clear.

If it is white + green elements, it will be more environmentally friendly (like my avatar, click me?)

If it is black background + red elements, it will be more punk. Gloomy (please refer to the Aimeili series brand for details)

I prefer the above colors

3. It is best to play the environmental protection card, which is simple and easy to understand. You can refer to GREEN PEACE. Some advertisements have been inspired. A tree and a peace dove are also very symbolic. Don’t put too many quirky elements. Basically, if there are more than 2, it will fail. In fact, I think the most important thing when designing something is to stick to "one center point", that is, there is only one eye-catching position. I don't like it if it overwhelms the screen.

4. Do you want to make a finished product or simply submit homework electronically? I suggest you make a finished product. Canvas is a good material. If you want to show your environmental protection concept more, you can try to use materials that are in line with the environmental protection concept.
