Here are some general composition tips: Every human knows whats aesthetic and what isn't, and pretty much everything in the nature follows the rules of aesthetics, or more specifically, the teachings of the golden ration. Its all about proportions. What is the golden ration? The golden ratio is how you divide lines. Imagine you have a line going from point a to point b: a ---------- b (ab=10 units). According to the teachings of the golden ration you would divide it by about 1.618, which would result in two segments like this: a ------|---- b (a = 6 units, b = 4; "|" is there for visualizing that there are two lines now. These proportions a/b = 1.618 can be found anywhere; car designs, architecture, arts, plants, humans and many other places. Ex. The length of your upper arm divided by the length of your forearm should be about 1.618. The more it differs from the value, the more unaesthetic you are. The value you calculated on your arms stays true for your whole body, you could get the same results with your legs. Now, you're probably wondering how the hell that can help with composition. Just like the lines, don't place your renders and stocks directly in the middle, it looks bad, and you know it. It makes no sense to always calculate the sections, so their ratio is 1.618. That is simple impractible and would take too long. Instead, movie is slightly to the left or right, you'll know when its in the right position. If you found any of this interesting, feel free to visit wikipedia and search "Fibonacci" or "The Golden Ration".
Or use the rule of thirds. But they're basically the same thing. Just the rule of thirds goes vertically as well as horizontally.
