@Nathalie-Kranich -- I had the exact same reaction as @Jeremiahbrown -- scrolling down in your portfolio, your work gets stronger. Why not lead with that?
In a recent SCBWI webinar, an editor/art director discussed what they look for in portfolios (of course, they're just two people, but I personally found their feedback helpful and want to pass it on). They suggest leading and ending with your strongest pieces. For them, the sweet spot as far as how many illustrations they like to see is around 10 to 15.
With that in mind, perhaps you could trim your portfolio a bit to allow the strongest pieces to shine and so they don't get lost? (It would be a shame for an impatient art director to miss your robot & flower illo because they got tired of scrolling.) Organizing your portfolio as a gallery rather than a carousel is a wise move -- it allows the viewer to choose which piece they want to see more of and linger over. Good job.
And it goes without saying that this is only my personal opinion. Your portfolio is beautiful and your storytelling is superb. Love it!
