That elephant walk in the disclaimer page is fantastic. Really realistic, except maybe a little too fast going from point a to b :)

Ok, let's start at the beginning. That first disclaimer on enter when the cookie is not already created, could be done via pop up or in the left/right bottom corner, that would be better regarding UX, but I'm sure you have a special reason why is it like that.

Now to the colors of the site. The color of the logo is blue, but the main color of the page is not really complementary to the color of the logo. And I don't really like the feel of it. It's too serious. It's not a great fit with your nice animations. You are mixing too much of serious and fun. Try to find that balance.

Now to the animations part. Like them. Creativity is in you! Can see the process behind it, a lot of moving in the Illustrator and making sprites :) They were all vectors, but now you have raster png's. More efficient way would be to save them as SVG and animate the svg.

This is an interesting case...

But I'd like to say first that as a user, you freaked me out right from the start :P I suppose this disclaimer is there for legal purpose, but come on, I was very close to not enter at all! There should be another way to display it, and another wording to make that a bit more friendly.

Concerning this "unusual approach of corporate web design", I have to agree with the "unusual", and thumbs up for trying to innovate. However, I have to be honest and say that it perplexed me. In fact, I don't know if this mix of illustrations (who are nice btw) favor or not the seriousness of the business you are promoting, and I don't know if it will manage to properly speak to your audience. I assume you choose that creative strategy in order to soften the image of finance, which nowadays is felt as an austere and a full-of-shark world. But as soon as I saw the portraits of the senior management, the magic stops, as the way they are dressed, the way they pose and they were pictured reminds me of.... sharks. And this creates a dissonance between the cool and friendly graphics and the reality. Of course, this is my opinion, and I just want to be proven I'm wrong ;)

Concerning the layout, it's very simple, even monotone. You could work on the fonts which contribute to that monotony. You could pick a serif font in order to create contrast and bring back a hint of seriousness.

Once again, thumbs up for trying to innovate, your site is an interesting case study ;)

Illustration here is great but personally think that you're relying too much on illustration which makes the site looked unfinished. Hopefully you can improve your styling on your site. :)
