Previously, Thank you for your review @oups. I have made some mistakes as you said.

In the clock indication, I make time randomly. The blue indication indicates the remaining time. Maybe it seems that this is complicated to understand if it is without hierarchy.

I designed this logo in inkscape. Then in the illustrator I just checked the error with the features it has. And also I export the file format to EPS, AI and PDF through Adobe Illustrator.

I do not know that there is a logo that is similar to the logo that I designed.
