Looking back on your other submissions this isn't much of an improvement. As far as quality is concerned it is lacking in effort. You may find it much easier to work with a wacom pad or tablet. Scene composition is likewise. And in terms of effectiveness as a teaser trailer, it really doesn't do it for me, though that is just a matter of preference. It's straightforward and uninteresting. I really enjoyed the teaser trailer for Cloverfield as it avoided shots of the monster and Star Trek as it featured a simple starfleet logo accompanied by classic "trek" audio. Perhaps you need to take some time researching relevant material before tackling a new submission.
