Hello There, 

Before I answer your query, let me tell you if you choose a career based on high monetory gains, then it would be a wrong choice. Since money follows skills or talent. Sometimes a high paying profile may not suit you because you may not have the required skills or potentials.

So before you make a choice crosscheck your skills with the skills required in the chosen career and if they match go ahead with the career choice. Incase you are not able to pinpoint your potentials, opt for an Aptitude test or career counseling test which would highlight your potentials and help you make a choice.

In terms of web designing and animations. Please note both are a high paid profile. One cannot compare the two. But when it comes to promoting or marketing a product to reach customers, advertising is important and if the advertisement is animated more chances of reaching and attracting customers.

At the sametime knowledge of web designing can come handy. Please note these days every second person wishes to be an entrepreneur. They need a website to promote their business. Thus knowledge of web designing and animations works towards a great advantage.

Another point of interest here is a web designer can work in a corporate and at the sametime freelance or work from home.

Hope this helps.

Wish you good luck...
