Playing with processing styles

I've been playing with Lightroom's sliders to see what kind of effects I can get to get more impact while ensuring that the processing is in keeping with the subject matter. These 3 shots are of people that live on the street and/or work as pavement artists. I'd be interested to know what you all think.

I don't think this guy is homeless; he just makes money doing pavement art on Trafalgar Square.

I like the first one best. The second and third seem slightly OOF possibly due to camera shake.

The first one has a great look to it. His drawing on the ground almost looks embossed. I'd say maybe pull back the "clarity" because the line it forms on his drawing arm between the white and shaded part is very strong.

Ok, KAS. Thanks for your comments.
