I would add the cells to the picture #2 as put as many green dots all over the photo, so that it shows the fish eating the cells! This ties your product to your label, and people remember it. I would center the words on the bottom. If you can change the font background to like a blue and rounded corners, it might make it look smooth. And capitalize the Phyto on the top to all caps, looks more pro. Man, I should be like a marketing guru. LOL.
