problems

Waves
i struggled for a while finding a tutorial/plug in to help create waves. i found one eventually but was not on time with my timeline, and therefore could not explore it as much as i wanted

Waterfall
learning how to use emitters and particle was hard, there was a lot of fine tuning to get it right, the water keep coming out gloopy and didnt look like water, was more of a lava/slime effect  

Colour
trying to find a color palette and apply it, too many colours, colour didnt suit the scene

Time/animating
was running out of time cause spent too long trying to figure out the waves and finding a nice color palette took much longer then expected. could spent as much time animating as i wanted to, wanted more subtle animation in background, trees swaying in the wind , light house and just overall correcting the timing of what i already have animated.

Sky
From having trouble with the color of the scenes made it hard to find colour for the sky that didn't mess up the color palette, for each scene i wanted to show 3 different times of the day morning, noon and night. i wanted to get this right because oahu had some fantastic sunrise and sunset which made the experience much more enjoyable. i ended up using actual photos of the sky which seem to fit in really nicely with the scenes and color.
