Pretty good.
Nice enough graphics for your first attempt. But I must say. You need more of a storyline to set up your first episode of a series..(that is to come I assume?).
It's a good idea. But you need to introduce why the 'Mask of Power' is so good..and why the evil boss wants it.
I like how you had birds flying, and also a mouse stealing cheese and moving around, whilst the other action is going on.
Make your text better. Make everything more "stylish" i.e. Make your text in boxes..with say and arrow for users to click on to go to the next frame of text. Make your text a custom font..or better color. Set things out differently.
Also try and polish up your overall look..
Otherwise, a great attempt..trust me..mucking around making movies in Flash really helps you learn.
I've learned a whole lot more..from when I made my first and only movie on NG.
I like your work. So keep 'em coming demodrgz.
If anyone doesn't like this movie, that's fine..if anyone criticizes this movie without any real thought or constructive ideas. May you forever have your hands slapped repeatedly with a large plank of wood.
Thanks.
