you should have set up a better enviornment for photos, maybe use something thats less of a powder so you get more contrast instead of a fluffy mess. make a nice white background (some white posterboard maybe?) put a little water on the cone and do it again.
and get some more light sources too. they all look kinda dull to me, but it could be the flour everywhere.
also, make more of a composition out of it instead of just a snapshot. maybe angle the camrea and do a 3\4 view of the sub and USE THE RULE OF 1\3!!!
