I'm no photographer bit as was already mentioned, LIGHT is the key (and a steady camera). Ideally, in my photo, there shouldn't be any shadow. The subject should be "surrounded" by light, of equal intensity on all sides and of sufficient brightness to bring out the real color's. In my photo, the light is good but back-light is insufficient, which causes the shadow. At least that's my opinion. I have a good friend that is a professional photographer and I'm gonna run this all by him next time he's over.
