Its always interesting when designers use illustrations + animation to inject personality into their agency sites. And on the whole, I think the site has potential but it lacks refinement in several places.

Id look at adding a bit of contrast between your illustrations, typography and your background. Some of your panda illustrations dont really work against the white screens and your homepage content tends to disappear on your light grey background, especially on larger desktop monitors. But most crucially, your projects page seems to be glitching when we hover over it.

Again, I liked the overall effect youve tried to create with the floating pngs within each project container but it definitely needs refining. In terms of clarity, your How we do it section is spot on in the way youve illustrated the site building process as the user scrolls. Overall, Id say good job but dont stop working on it just yet.
