The shadow is not very good, the shadow drawn directly by cdr is very rough, and it is stiff when superimposed with various colors. And every time you change the size, it will be recalculated, which is even more unreliable for a logo.

The transparency effect depends on how you use it, which is relatively stable relative to the shadow. But if you make a translucent sign ... I don't see it very often. Think about how to maintain its performance in various light and dark backgrounds. But this is a design problem of logo, which has nothing to do with the CDR you asked.
