Almost perfect...
Ok Kine_the_Genius, let me tell you whats keeping this movie from being the #1 rated NG film.
The graphics are top 5 material. That isn't in question. Your animation and graphics are SUPERBLY done.
Now the bad parts.
The music, while it is from Kirby, didn't fit the action. Just because you're trying to follow a theme, don't feel forced into using only Kirby game songs. You should have used a song with more energy to it, some more power and speed. That song was too bland in my opinion.
Second of all. I know you were trying to make the film with the action based around the song, but please, use some sounds! Even if you just had some explosion, punches, and other sounds, it would've made this movie #1 material.
If you are in the hunt for greatness, I suggest you utilize my suggestions and put out a second version of Ambush, with more fitting music and better sound. These flaws bugged me more than any other movie with the same missing features, because this is one movie that should be in the top 5. Good luck in the future, yours is a bright one!
