Some peeps will argue about this, but your pixel ratio on your uvs is a little off. It would be ideal for you to get the most out of your textures by having everything relatively sized proportionally to the body.
One thing u could try ( this will mess up your uvs, so dont cry, cuz i told you so ) grab everything, and do a relax. This will shink down some parts, enlarge others, and in the end give you equally scaled uv islands. After this you will have to go back and do some fixing to get your uvs to be as neat as you have them.
The thing with this is that you are giving more uv space to the shoes and not the shirt. Whatever texture you put into the shoes will come out sharper than anything that you put on the tshirt. the hands, use as much space as the head. Are you going to be painting nail designs on those? a tattoo maybe?
