At the end of the day, there are many aspects of animation (and all video production for that matter) that really can’t be entirely taught... good composition is one of those areas that CAN be learned, but requires God-given talent and a lot of practice to perfect.
When you begin putting your text into place, try to maintain equal spacing between words. It’s easy to let things slip, especially with words poppin’ up in all different sizes and angles, but in general be sure your spacing is relatively even across the board.
Additionally, there is something aesthetically welcoming when the invisible lines created by the letters are aligned. I’ll often create a quick null object and stretch or rotate it as needed to give me an accurate reference. When you look at the composition of your current frame there is a general principle that if you have an even number of elements, it will convey more symmetry and structure... whereas if you have an odd number of elements, it will convey more creativity and fun.
