re: "I am new to Upwork and am trying to create my profile. Is there a way I can create it without uploading a picture of my face? can I just leave it, or just put my logo there instead?"
Yes.
If you intend to use Upwork only as a client (not as a freelancer), then you do not need to have a profile photo. Or, if you prefer, you may use a logo or avatar or other image.
Alternatively, you may create a freelancer profile on other platforms (not Upwork) which do not require profile photos.
