Judging from your experience and album design level, it can only be said that it matches your salary of 5000 yuan. I don't know about Dongguan, but if you have this level in Beijing and Shanghai, it should be 7-8 K. It's still easy to find a job. In fact, your question is simple:

You need to improve your aesthetic and design level, and your salary will naturally go up.

The software is not good enough, of course, more will give you extra points, but first you need to work hard on your main business.

As for finding a job, it's definitely a matter of probability, depending on luck, it's urgent.

Suggestion:

Vertical development: You need to improve yourself as soon as possible, study in depth at the design level, read more works by foreign masters, and upgrade your design level by several grades, and your salary will naturally be high.

Horizontal development, such as learning some web design, should not be confined to the plane, which will increase your chances of finding a job.

Learn some plane-related software. For example, if you mainly do packaging, then packaging needs some simple renderings. If you know C4D, you can easily make textured renderings, which will make your design work soar.

Finally, it depends on how you plan your future. Are you only satisfied with 6000? If you don't study to improve yourself and want to get a salary of 6000 at the current level, then you will basically reach the ceiling in the future.
