Working within constraints

After we came up with the idea for the project I started working on it immediately. I started with drawing boat that is floating in a sea/ocean. wave animation was created by drawing the frame by frame and boat movement by tweening it.

It took about 8 seconds for animation to reach diveing part of animation. About at that point we were told the actual size that our animation has to be 750x480 so I had to redraw parts of animation. After  boat and diving stages were finished my team mate finished drawing seabed, fish and trash. I imported all the images to flash and decided where everything will be. After that I started scripting. After i finished scripting there was 166 lines of script so I decided not to write all the script in my blog.
The last thing that was left was to make still image of shark and school of fish appear as they are swimming. I achieved this effect by using puppet warp on Photoshop.
