Hello, I'm an advertising major, specializing in graphic design. I hope I can help you.

The theme is snack bar, so there is no need to make it fancy. I don't suggest that you make the background subject light green.

the snack bar should highlight the old brand, even if you are newly opened. In color, "black" is the best background, which reflects steadiness/aging, and the most important thing is to give the audience a sense of food security invisibly.

The font "Fujian snacks" is in the form of a brush, and the style is your choice. Either "red" or "gold" will do. Red can stimulate appetite, and gold embodies the ancestral formula. Either way, choose.

You can also design the signboard in a simple way, such as deliberately making some wrinkles and cracks. Signs are suggested to be wooden or wooden. Never use plastic or something similar to it, or you will feel inferior and affect your appetite.
