Thanks for your feedback .... tell, if it is an imitative counterpoint because it will tell you: If you look closely at the score, there is a repetitive motif (imitated) and most often mutated, and with only this comment is imitative, imitative counterpoint is also characterized by always start with one voice and switching the supposed reason for the mimic each other's voices. It is an imitation mutated due to the technique of paraphrasing that used the great Palestrina. This paraphrase, is responsible for altering or gloss over the subject a little, to give variety, but always without losing its essence. Imitative counterpoint is without mimic a free-form idea, with few restrictions, hence it is a good year of study. In the treaty of Fux (treatise Viennese Baroque composer) makes it clear that it is imitation, or simple but not least wikipedia.
