A. Logo design is the representative of brand image, which is very important for an enterprise or brand.
B. A good logo is the icing on the cake. Bad logo brings you destructive image propaganda.
C. The refinement of a brand designer requires the study of professional knowledge and practical experience. It's free or low-priced. You can call a designer after studying PS for a few days.
D. Professional people don't waste time here for grades.
E. I suggest that you should take the image building of your company seriously and be responsible. Using one casually is like putting inferior cosmetics on your face, and the consequences can be imagined. If so, it better be true. These are my suggestions as a brand design practitioner for many years. It depends on how you know. I also have this information in Baidu Space for your reference. All are personal opinions, for reference only, or you can contact me for communication or design.
