Your drawing style is unique, very creative, and is incredible. There was a lot of work put into minor details of the animation, which made it stand out. Examples of this are how you used several different shades of brown to make the title of the flash, how you used 2 different greens in the her eyes to make them look more real, how well drawn the seagull is, how you made sure that the clothes chest had nails visible etc.
Things about the scenery were drawn well, but i did notice somethings that could have been improved. The water scenes where you see the water moving. I think it would have looked a bit smoother if you drew in more basic water pictures, it would make it look less choppy, and more smooth.
Another thing is that you have conflicting winds. In the beginning, you see the flag blowing in the wind, towards the left side of the screen, but the clouds, as well as the water are all blown to the right.
One last thing that I noticed about the clouds, is that in some screens the clouds are staying perfectly still, and right after you have them moving. This is just another conflict with wind effects within the flash.
The background music of this animation is perfect. It fits in so well. It is this adventurous music, which in this flash that is what the main character is being set up for. There is no sound effects, but that is ok because it would have distorted the background music. You also drew in slides and made notes of the sounds taking place, which makes us know that you didn't forget about them.
The last thing I could suggest is that you add "Stop ();" into the actionscript on the last frame of the flash. That will stop it from looping.
Overall this is a great first flash, that is well drawn, and I can't wait to see more from you
