This is a pretty damned good start!!!!
This is your first flash movie??? Wow... You spend like a month on making those graphics, or are you just some miracle-kid? ;-)
No, I liked it! It's a shame there wern't any sounds... But hey, I survived it without any ;-)
Anyway, I don't think you need that much suggestions for your animation => the graphics really looked good!
But one thing => when the spacecraft goes on its voyage, that takes too long, and it was too boring... Maybe that will be better if there are sounds in it...
And qua music: what kinda music are you looking for? Are you going to take soft music, or some hardcore metal?? =) I'd suggest something in between. But please, don't take something noone has ever heard off... I always find that annoying with those space-movies here at NG... Their music is always boring...
AND PLEASE: don't make it boring!!!! :/
Anyway, you've got my respect!
Keep the good stuff coming!
