This looks pretty cool so far.
I like some of the drawn animation used for the movie and how to manipulated already existing video game sprites to do a bunch of poses.
The trailer was very fast moving and didn't allow enough time to soak everything in.
I like the effect of moving background clouds in one shot.
I seen a lot of cartoons not even bother to use the motion tween feature to move clouds.
It's a very simple effect to do and it looks cool.
Other shots had a semi 3D look and was used to enhance panning shots.
You have created a decent looking trailer.
I'm personally not a fan of these sonic fan movies.
If you can also create original characters and use the same kinda effects too.
Creating original sprites would be awesome as well.
Best of luck to your new movie.
Once I get everything finished up with this I do intend to move on to more original works! I have plenty of ideas but right now I don't have the time nor the resources. And I certainly don't want to leave this incomplete because that's one thing that irritates me! People starting something then never finishing it.
Wow this is really nice!^^
Looks pretty AND exciting! Good luck.
