Hi, sir this is not a copy art from your link provided. please notice that the picture on your link was wearing a shirt and shoes while mine is not. my picture came from the attachment file from the client attached files in his brief I just extracted the gear clipping mask on that file and color it black since I know that the client still wants that running man in his logo. please review again, It will help you to understand that my designs was not a copy from any other. Cheers!

my advice to you is always read carefully the brief in order for you to win. this is the client wants on his logo. I will quote it for you,
"- My current logo is a 'gear' man running, which is nice, but not able to print or embroider onto shirts/clothing/etc because it is very intricate. I wouldn't mind keeping the same kind of concept." that's what the clients want. he wants his running man. :)

wouldn't mind means = You can use this to politely.
