While you did take the models from a different source. The animation itself with the dialogue is done fairly well. Although there was a good bit of static background to the audio that could have been cleaned up in an audio program.
Overall it was a bit short, and seemed to end rather abruptly. Almost as if you lost interest, and decided not to finish it.
All this aside, an additional reason I am writing a review is because of the E label rating for this video. Not to hound you, but if you're going to include cursing and other lyrics more suited toward a mature audience, it shouldn't be rated as such where the youngsters think it is fine. Especially with pokemon as a theme to draw them in. T would be better suited for this.
