If you want honest opinions: The Boxes textures look too syntetic too me. How about to use a camera to take some pictures from real boxes, I promise it will look more realistic. However, you have to take care for it must fit in your current game design style. And although I highly respect your work I found it a tiny little bit too clean.
But of course this is only my personal and maybe not very relevant opinion.
The human model look very good.
