looking into animation styles

i started looking into animation styles to try and decide what art style i wanted to go with and i was surprised by the amount of different ones available. a few videos i looked through stood out to me.

I love the way this animation flows with the music in this video, using burst of colour and images.

the hand drawn illustrative effect looks really eye catching but with the time span we have i don't think i would have enough time to do an animation in this style with it moving to the music and animating all the small parts so i look further into more cartoon styled animations.

a video where a picture of a line of birds has created written music using different transformations in after effects.

this animation uses alot of the effects found on after effects such a fading the pictures out using the opacity and also scaling the image to zoom out at the begginning. this animation is really simple but effective although i don't feel this is the right direction i should be going in.

I love the hand drawn style of this animation and I’m thinking of using this as my drawing style

all of the illustrations blend into each other and create a really nice effect of story telling. this style is something i personally find the most attractive but i'm trying to aim my animation more at children because their are the next generation to look after the planet and i don't think this will cause them to stop and stare. i need something more cartoon like and colourful, so i started looking at disney animations to see how they target the audience so well.
