Primer style is characterized by too many short sentences. It is important to note that there is nothing inherently wrong with short sentences. Too many of them in a small space, however, can remind readers of material they read in kindergarten or first grade: See Dick. See Dick chase Jane. See Jane run.
Used within a mix of sentences cut to various lengths, short sentences can be extremely effective as they are capable of focusing the reader's attention on a particular point. Look at this one. See? A quick review of your text, however, could reveal an overabundance of short sentences and the need to combine some of those sentences into longer structures.
