Erm, still a little glitchy
I noticed alot of glitches that you should take a look at: 1) the pelican has a shadow underneath it. You should get rid of it. 2) some of the sprites don't follow the proper motion tween path.
Im just trying to help, and my second submission has a few things wrong with it as well (click on my name, and check out my favourites.) Um the reason i think i did a better job on my 2nd submission than you did is that for one, i know which Sprite Sheet you used and it doesn't have any walking animations, and 2 I think I fooled around with flash a bit before i actually made something.
Then again im still a noob at flash so who am I to talk
