Well here are some suggestions that you might try. (Please don't see me as too judgemental here, you did ask and I'm gentle as a kitten.) 1. I would lose the horizon line. It is very distracting, the first thing your eye goes to when you look at it. Then the objects have to compete with it for attention. You could paint it out in post work, or if you're keen on a re-render, turn fog and haze off. Or you could change fog and haze to a shade of blue that blends in with the rest of the background. IMO, this may be the one thing that is keeping you from feeling it is finished. The next suggestions are more about possible improvement from my POV and a little more subjective on my part. Feel very free to ignore them. 2. I would enlarge the martini itself. I think the image would benefit from the focal point of the piece taking up more space. 3. You could place a cocktail napkin in the pic with the logo of the bar (if available)on it. This would give you an excuse to have the name of the bar a little larger in the picture as this is meant to be for advertising purposes (I'm guessing). Also this would be cheap to do computer-wise because you could do it with a 2D Pic in Bryce. As far as your last question, metaballs are exactly like spheres except when you put them close together- then they physically run and blend into each other. But only when rendered, you won't see this in the wireframe. Hope this helps. Render on.
