nice! are you planning to take all of these assets to game level? within a game art context it seems a little odd to handpaint all the lighting information directly onto a highpoly model (the saw), and some small details on the fan might get lost at the bake stage.
I like that you got such a clear path to improve :) The handpainted wood texture looks quite nice, you got a good sense of shape and form, however I think it could do with stronger contrast and some more color. The same goes for the shield, the shading seems flat.
