Please tell the advantages and disadvantages of these two posters.

The advantages of the first type: fresh color, reasonable and clear layout, clear and obvious text.

Disadvantages of the first picture: the title text is slightly small and not prominent enough. The QR code is too low and there is a blank on it. Why not move up a little? The overall layout is slightly repetitive and a bit vulgar.

Advantages of the second picture: obvious color contrast, prominent title theme, reasonable and clear layout, and layered text and illustrations.

Disadvantages of the second picture: the text color is single, so you can use yellow to highlight some chases on such a dark background. For example, the title can be changed to yellow, so that the text has color levels and will not be too monotonous.
