The model forgot to make up her hands. “Always watch their hands!” is not just for movies. The hands did not fit with the rest of the look, and even clear nail polish on a guy looks strange. Also, the cap & gloves were too clean.
Not to belittle the idea, but a little water, some dirt, and some grease can do a lot without needing a full make-up kit. It dioes not need to be perfect, just “good enough”.
