Not really anything special. Try to: add a more interesting background; improve the text to something clearer and more unique; add more frames to the animation , as it seems very jerky and dull at the moment.
The animation is too immediate and does not last long enough. For a better effect I would Recommend having it fade in. (Fade out if you want). Also have it show all the text longer. If you prefer not to have it fade, have the other text and the side art pop in and different times and make sure to have the frame with most of the text last a bit longer. Also, More Frames in this case would mean a better effect and transition.
