those are good pictures. the only tip i would offer is to add a little variety. if you notice in all of your pictures, the knife is pointing to the left. in fact, only one is pointing something other than down and to the left. my guess is you are right handed, and that is the hand you put it down with, hence the orientation.
i dont think there is anything wrong with them individually. they all seem well laid out and everything else. as a group, that was my only critique.
i actually really like the second one. is that grape vine?
