Oh my god, Shadic, it's amazing! I could never do anything like this. However, as a perfectionist, I'd like to point out things to improve. 'Cause choo MUST WIN!
* Any time there is an area in which you see the dragon, don't give more than a second to wait for it to come on screen.
* The opening gave me enough time to read, but shorten it by just A LITTLE bit, keeping it on the screen too long will disinterest, as well as you should most likely title it "The Dragon" instead of "A Dragon."
* The Dragon should be more detailed [I have a feeling you planned on this, so sorry for repetition], but a more detailed dragon will fascinating. Mostly, the face looks goofy for something as cool as a dragon, and the wings are REALLY stiff.
* The terrain is too similar to each other in each scene. Adding trees, shrubs, or muddy hills might help this.
* The trap or thing that attacks the dragon is too bland... I can't really tell what it is. To fix this, you might want to use some brighter colors or have it more defined in that scene.
I'm sorry, I didn't mean to pile up with the things to fix.
But it's great, and has A LOT of potential to be better! <3
